Jurassic Park and Suess at IOA are 2 of my favorite themed "lands" in any park, regardless of attractions.
The "Bugle offices" section of the Spiderman queue is very odd and cheap looking. Even if it was painted different colours it would look better, but what's the thinking behind everything being grey?
As for rides, MIB is fantastic (a big part of it's appeal to me is the queueing area, so heavily themed and inventive it would work as a stand-alone walk thru), Jaws is a must and Hulk is my favorite coaster anywhere - great launch.
In an upcoming 2 week WDW trip, we are taking at least 2 days out to visit USO and IOA (and one each for Busch & Seaworld).
