These cannot be missed:
MK - Space Mountain (a classic - ride the left track, some people say there is a difference, others say there is not - the people like me that do say there is a difference though always say the left is better!), Splash Mountain (again, a classic, plus the story you see as you ride through is the cutest! Ride the front!), Big Thunder Mountain Railroad (ride the back if you like speed, the last car is the fastest), Philharmagic (hint: it combines most of your senses), Wishes (awesome fireworks!), Spectromagic (soso pretty!), Buzz Lightyear Space Ranger Spin (very fun, it's a laser shooting game, you move in a car that is stationed on a conveyer belt that moves past all these targets, and you can spin the car.)
Epcot - Test Track, Turtle Talk With Crush (it's amazing how they do this), World Showcase (get a funnel cake, buy candy from Italy, and YOU MUST SEE the show they put on in England, I believe the group is called The World Showcase Players, it is SO funny and one of my favorite things to see in Epcot), Illuminations (I am not a huge fan, but you must see it atleast once. Try to get a space over by England about a half hour before 9pm, it's a great view)
MGM - Tower of Terror (the hype is scarier than the actual ride), Rock 'n' Rollercoaster (by far the best WDW rollercoaster), Beauty and the Beast (although it's very fast paced, it's beautiful, and it doesn't really take away from the story at all!), Fantasmic! (the music is awesome, the whole thing is just great)
AK - Dinosaur (really fun ride, pretty much completely in the dark, really fun), It's Tough to be a Bug (the cutest show, and like Philharmagic, combines your senses)
DTD - World of
Disney store (they have EVERYTHING!), Disney Quest (we spent hours here, we LOVED it, so many games and we loved the interaction - we could have played the Buzz Lightyear bumper cars all day!)
Also, here are some places you may want to dine that I and many others enjoy:
MGM:
-50's Prime Time Cafe (lunch/dinner - the waiters/waitresses act like Moms & Dads, tell you to get your elbows off the table, set the table, pretty much pick on you)
- Brown Derby (lunch/dinner - modeled after the restaurant of the same name in Hollywood; expensive, but a great dining experience)
- Sci Fi Dine In Theatre (lunch/dinner - if you make a PS and are not a walk in, you sit in a car - literally - and watch old Sci Fi trailers and theatre commercials - TONS of fun)
Epcot:
- Alfredo's (Italy, lunch/dinner - GREAT Italian food! Awesome Fettucine Alfredo, very romantic setting.)
Magic Kingdom:
- Crystal Palace (breakfast/lunch/dinner - I have eaten here for dinner, and the dinner buffet is TO DIE FOR! So much food, very yummy. Plus Pooh + friends come around and greet you!)
Resorts:
- Beaches and Cream (at the Beach Club - dessert - BEST sundaes!)
- Chef Mickey's (Contemporary, breakfast/dinner - I always get breakfast here, Mickey & friends come around in chef outfits, GREAT buffet, TONS of food.)
- 1900 Park Fare (Grand Floridian, breakfast/dinner - characters come around, buffet, AWESOME food, by far our favorite breakfast, plus it's at the nicest hotel on Disney property.)
- Whispering Canyon Cafe (Wilderness Lodge, breakfast/lunch/dinner - ASK FOR KETCHUP! Very fun, just make sure they don't seat you in the back. GREAT food for every meal!)
DTD:
- Ghiradelli's - great ice cream!!!
- Planet Hollywood
