Some of my favorites are Expedition Everest (Animal Kingdom), Tower of Terror (Disney Studios), Toy Story Mania (Disney Studios - my family's absolute favorite!), and Mickey's PhilharMagic (Magic Kingdom). When are you going? Summer time can be brutal for some of the lines. My favorite time of year to go is October. A lot less people go then. One other recommendation if you are going with kids: A fun place for dinner is Mickey's Backyard Bar-B-Que in Fort Wilderness Campground. It's an outdoor covered pavilion with a buffet of typical barbeque/cookout fare, but the best part of it is the close-up interaction the kids get with many of the "core" characters. A band is playing music and the kids get to dance with the characters on the dance floor. We have had so much fun at this dinner many times! Reservations are a must. Have fun!
