Spiderman is the best ride in Orlando located at IOA. Try to do this first. Car can spin, bump, raise and lower. 3D attraction makes you feel that you are in a Spiderman Cartoon. Other attractions at IOA; Hulk, launced Roller Coaster with many inversions. Jurassic Park, Jungle Cruise on Steroids. With Plunge at end. Dudley Do Right, Log Flume ride with the best plunge at the end, You will get wet. Popeyes and Bluto's Bilge Rat Barges, Best Raft Ride around, You will get wet,wet,wet and more wet. Duelling Dragons Suspended Roller Coaster with Inversions. What makes this coaster Unique is many near misses with other Coaster. Try to ride Ice Coaster in Front row. Posiden's Fury, Nice Stand-up attraction passing through three chambers, Water Tunnel is great. Cat in the Hat, Very nice dark ride based on the children's story. Other nice things are One fish, two fish, Carosuesel, Storm Force and Flying Unicorn.
At USF, a Movie Based Theme Park with rides based upon the movies. Quite a concept when you think about the other Movie based theme park in Orlando. MIB, is sort of like Buz Light Year with Interactive Scoring, except the Z's don't fire back. Quite a unique ride that makes you want to ride again and again. BTTF motion simulator with Movie, Mummy ride, Combination Dark ride and Roller Coaster, the best. JAWS open area dark ride battling the famous Bruce from JAWS I, II, III, IV, and whatever. Earthquake, most likely next USF ride to get upgraded. Most likely the first and Second Best 3D attractions; Shrek 4D Great movie with an added D. Terminator, Come watch the Gov. of California wipe out those "Girlie Men". Other nice attractions are ET, Universals answer to a small world, Jimmy Neurtron a Motion Simulator ride, Twister, stand-up attractions, Woody Woodpecker Kidzone.
My only tip, stay at one of the Universal Hotels and get unlimited express passes for all the rides. Otherwise get there early and ride the major rides first.
