You guys have it all wrong. Islands of Adventure is NOT an amusement park, its painfully obvious that its a theme park! Every part of it is themed. Each "Island" is a different land, exactly like the lands of the Magic Kingdom!
I'd also like to point something out: Here are the top 20 attendance figures for 2001:
1. The Magic Kingdom at Walt Disney World, Orlando, Florida, 14.7 million, down 4 percent
2. Disneyland, Anaheim, California, 12.3 million, down 11 percent
3. Epcot at Walt Disney World, 9 million, down 15 percent
4. Disney-MGM Studios at Walt Disney World, 8.3 million, down 6 percent
5. Disney's Animal Kingdom at Walt Disney World, 7.7 million, down 7 percent
6. Universal Studios at Universal Orlando, 7.2 million, down 10 percent
7. Islands of Adventure at Universal Orlando, 5.5 million, down 8 percent
8. SeaWorld Orlando, 5.1 million, down 2 percent
9. Disney's California Adventure in Anaheim, California, 5 million, opened in 2001
10. Universal Studios Hollywood, 4.7 million, down 9 percent
11. Busch Gardens Tampa Bay, Florida, 4.6 million, down 8 percent
12. SeaWorld California in San Diego, 4.1 million, up 13 percent
13. Knott's Berry Farm, Buena Park, California, 3.58 million, down 3 percent
14. Six Flags Great Adventure, Jackson, New Jersey, 3.56 million, up 1.7 percent
15. Morey's Piers, Wildwood, New Jersey, 3.4 million, up 3 percent
16. Adventuredome at Circus Circus, Las Vegas, Nevada, 3.4 million, up 7 percent
17. Paramount's Kings Island, Mason, Ohio, 3.36 million, up 4 percent
18. Six Flags Magic Mountain, Valencia, California, 3.2 million, down 3 percent
19. Cedar Point, Sandusky, Ohio, 3.1 million, down 9 percent
20. Santa Cruz Beach Boardwalk, California, 3 million, no change
Look! Universal and Islands of Adventure are RIGHT behind Disney! Which is exactly what they want. Not too shabby if you ask me.
