I thought that these ideas might make a fair addition to the Hyrule section:

Zoras Domain - An indoor area where there are stores and restaurants.  Similar to The Land at Epcot, except themed to Zoras Domain from the N64 game.  Waterfalls and Zora statues are everywhere, the entire place is lit in blueish-white light to enhance the experience. In the center is a pond, fed by the waterfalls, where Princess Ruto stands watching over her land.

Lord Jabu-Jabu - A play area just outside of Zoras Domain. You enter through the giant fish's mouth and find fountains, slides, and other standard fare. The lights are shaped like the anemone enemies from the game.

Temple of Time - An information center where there are displays chronicling the history and lore of the Zelda games. The triforce would be centered on the back wall and the master sword would be in the center of the building. Possible displays include the Ocarina of Time, the three spirit stones, a koriki tunic, and the biggron sword. The song of time would play softly as background music.

THERE SHOULD BE MARIO COSTUMES.

IT WOULD BE COOL TO HAVE ENTERTAINERS DRESSED UP AS THE CHARACTERS. THERE SHOULD BE A DONKEY KONG MINE RIDE.

PLUSH TOYS,MUGS,HATS T-SHIRTS,AND CANDY, FOR ITEMS.

YOU COULD PURCHASE NINTENDO GAMES TOO 

"First off, let me just say this is a wonderful idea.It's so good, I'm surprised I didn't think of it.  I have a ton of ideas:

All Worlds:

Cable Cars and Transports: selfexplanatory

Tingle's Maps and Information:  An information booth in the shape of everyone least favorite elf wannabe.

Themed Bathrooms:  Every theme park has them.  In Zebes, it could be Samus and Fox. In mushroom Kingdom, Mario and Peach. In Hyrule, Link and Zelda.

Game Stations:  Throughout the park there are various game stations. Nothing verylong, just something you can play for a few minutes, mostly multiplayer things,but some sidescrolling or puzzles would work as well.

Game Boy Advance Rentals:  Each person who enters the park gets one GBA, one Link Cable, and any 2 games of their choice to play whilewaiting on line. When you leave, you must either turn them back in, or pay the full price for them. You may also bring your own, it would say on your ticket.

In Mushroom Kingdom:

Cranky Kong's Classic Arcade:  Similar to the SR-388 arcade, but this one specializes in old school arcade, Game and Watch, and NES games. Of course, there are updated versions as well, and some crane games with some nice prizes. Of course, there are some modern games as well, but mostly classic.

Bumper Karts:  BumperCars in Karts: simple enough

Mario Mini-Golf:  A mini-golf course with a lot of small enemy-themed courses. Goomba,Koopas, Lakitu's, Buzzy Beatles, Cheep-Cheeps, etc.

Mario Kart (expanded):  You already have this idea, but this is an expansion of it. There is a choice of 3 courses, Luigi Raceway, Mario Raceway, and Peach Raceway. Each Kart is not on tracks, but does have riders along the edge so they can't get off the track. They're not very fast, so there is no need to worry about crashing into each other. The best part: Each Kart has three buttons on it that correspond to one of three weapons, shells, bananas, and lighting. Of course, they don't really exist, but they do the samethings.  Each Kart has Laser receivers all over the outside of it, and laser guns all around.  Around each course, there are painted lines on the tracks, and over these tracks there are lasers.  When you pass them, you gain a random weapon.  Green shells fire off a laser straight ahead.    Bananas fire a laser straight behind, and Lighting shoots lasers all over.  When one of these lasers hit another kart, it slows down greatly for a few seconds.  With three different courses, and people needed for maintenance, this would probably be a good idea as something separate from the main park. There are two entrances: one through Mushroom Kingdom, and one outside.  If you play through Mushroom Kingdom, you get a stamp and it is free.  If you enter outside without entering the park, you must pay a fee.  (I know it's unreasonable, but it's fantasy)

The Mario Brothers Pizza Place:  A restaurant specializing in Pizza.

Yoshi's Fruit Stand:  A fruitbar, sells smoothies and fruit salad as well as many other things.

In Hyrule:

Moo-Moo Farm:  A small petting zoo located rightnext to the lost woods. Perhaps there are Epona rides.

Happy Mask Salesman's shop:  A shop that sells mostly masks.  Buy your favorite masks from the Zelda games or you favorite Nintendo Characters Masks.

In Zebes:

ROB's Training Room:  3 parts to this ride:
-Combat Simulation: a Qzar-likemultiplayer game of laser tag. 2 teamsfight against each other, one being starfox, the other, starwolf
Target Practice:  Similar to the Buzz Lightyear ride at DisneyWorld in Florida.  You and another person are in a moving car.  You eachh ave a rotating turret laser gun.  Asyou move, there are certain targets you need to shoot and the harder the targets, the more points you get.  At the end, you receive a certain score.

Flight Simulation:  20 people per ride.  Each have their own Arwing Shaped video game that they enter.  Inside is a videoscreen, such as you would see on a game on Starfox 64.  You have a throttle, buttons for lasers,bombs, boost, slow, etc.  You playthrough a level, with 19 other arwings flying around.  They each have numbers, so if a friend is in number 15, you know which arwing he is.  You must cooperate to defeat minibosses along the way and collect power-ups.  At the end, all the arwings switch to all-range mode and must fight against each other.  The winner's arwing lights up at the end.

The Game and Watch's Classic Gaming Diner:  Specialty:breakfasts, Eggs with Sausages (of course).  Lots of specialty food names, like the Duck Hunt Pancakes

Now, the real addition: 3 new worlds

The Nintendo Game Center
The main spindle of the park.  After you enter the park, you start off here.  Around this place are many, many gamestations with most of the recent games.  Around are 3 large screens showing Multiplayer games such as Super Smash Brothers, Mario Kart, and Mario Tennis.  The lines will naturally be very long for these, but it would be worth the wait to show your amazing Multiplayer skills.  This is also where the lockers, primary bathrooms, primary information desk, and other important stations are located.  Between here and the entrance are a few basic shops that sell souveniers

The Nintendo Ferris Wheel:  Each Ferris Wheel car has a picture of a different Nintendo Mascot on it.

Pokeworld
This is the Pokemon section of the park.  This section is a very happy and peacefulplace.  The entire land is very ideallic and happy.  Here, you can visit Pokemon, Sugar Creatures, or the village of Onett. 

Professor Oak's Animal Show:  Professor Oak is sorry he can't attend, but his assistant can come instead. This is a semi-educational animal show. Professor Oak's assistant tells about different animals and how they are related to some of the kids favorite Pokemon,  (example, Porcupine and Sandshrew, Falcon and Pidgeot)They also do a variety of tricks.  A large video screen is behind the assistant so the kids can see Professor Oak once in a while.

World of Nintendo Pokemon Gym:  Here you may watch a 3-d movie ofa battle between Ash and Zack, the gym leader at this Gym.  He uses Legendary Pokemon, so you can expect quite a show.  There are also some effects like bubbles, water showers, air gusts, and some blasts of heat. 

The Mind of Mewtwo:  Tilt-a-whirl type of ride.  The circle spins faster and faster and moves at an angle.

The Warp Star: A smaller roller coaster, in this one, you ride underneath the star, a hanging coaster.  There are a lot of twists and turns on this one.  Not as large, but more thrilling.

King Dedede's Strength Challenge:  Regular strength test: your goal: hit the pink, Kirby-like bell with a metal gong using a mallet.

UFO Invasion:  A pirate ship type of ride.  It swing back and forth.  Around it are serene pictures of Onett.

Pop Star Sweets:  A candystore with some Kirby collectibles, their specialty: M-tomato Lollypops.

Ice Climber's Mountain Preserve:  An ice cream shop and air conditioned resting place.

The Villain's Dungeon:  This world is dedicated exclusively to the villains of the games.  Bowser, Wario, Ganondorf, Ridley, Lord Nighmare, and Team Rocket are featured here.  Beware they don't take you under their power.

Final Battle:  This takes place in the main building, right above where Bowser's dungeon is.  It plays twice a day and is approximately an hour long.  It is a combination of special effects, live-action performances, and a movie.  It shows the final battle between all of the heroes and all of the villains.

How to be a Villain:  A comedic movie.  Ganondorf, Ridley, and Lord Nightmare thank the audience for attending and try to teach them how to be a good villain.  Bowser, Wario, and Team Rocket keep joking around however, and somehow manage to trick the other three away, leaving the 4 of them by themselves to show what their version of good villains is.  At a few times during the show, you may hit one of 3 colors on a remote control. Whatever option that the majority of the Audience chose is the way the story will proceed.

Ridley's Escape from Zebes:  Movies show the part of the SNES game where Samus beat up Ridley, but after Samus leaves, Ridley is still alive.  After you board the car, you watch a small movie on the screen in front of you.  A roller coaster ride after that shows how Ridley escapes is next.

Meowth Balloon Drop:  The classic parachute drop but in the shape of the Meowth balloons.

Magic Training:  Ganondorf starts showing you magicand the room begins to spin. Classic Gravitron.

Wario's Woods:  An enclosed area where Wario has a few game stations and there is also a rest/recreation/shopping/eating area.

The Darkness:  Lord Nighmare sits here opposite the entrance and watches over people eating steaks, burgers, and other meals.  The only real restaurant in the area, it has some excellent food.  Kirby has appeared near the entrance with the star rod, leaving one side light, and one side dark.

I have a map, but it's not really good.  So here's just a brief description of what it would look like.  Spindle is in the center.  To the immediate left is the Mushroom Kingdom with the castle exactly to your left along the outside.  Going clockwise, you have Pokeworld, Villain's Dungeon (if you go straight instead of left), Zebes, and then Hyrule (if you went right instead of left) with Hyrule castle exaclty opposite Peach's castle.

Hope you like my ideas.  Enjoy."

• A full sized Temple of Time that you can enter. 
• There could be a Clock Tower that resembles the one in Clock Town in Majora's Mask. 
• Video Room-Would probably be in a general area.  It'd show the Super Mario Super Show Mario cartoons, plus the Zelda ones as well as the SMB and SMW cartoons. Perhaps the Pikachu shorts seen before the
  Poke'mon movies.
• In the gift shop, you said that there would be Mario hats, but what if a kid likes Luigi, or Wario, or Waluigi more than the guy in red?
  Music CDs both foreign and domestic of current and
  past games.
• Hardware and software from Nintendo.
• NES-style Zapper with sound and light effects.
• Nintendo character bobble-heads(personally I don't like them, but I know people that do).

• I like the flow of the park, but perhaps a Tram coupled with some more walkways would facilitate access to all areas, and add more sites for visitors to see.  Nevertheless, an excellent job !
