Example: Since I'm a photo-hog, I love having wild or even man-made scenery that BEGS me to take a picture of it. Like the Toon Lagoon of Islands of Adventure, there's all those floating thought bubbles that BEG a person to stand beneath it and take a picture.
Ooh yea... and more extra events! (Why hasn't there ever been a hip-hop/rock/pop concert that appeals to teens at the Busch parks? I think the concerts they bring in appeals more to the 30 and up crowd. Oh well, at least there's Howl-O-Scream...) Like maybe a Food and Wine like Epcot...

Am I missing one? Another avenue to go would be Scandanavia, which would be interesting as well.
In addition I'm not sure I would want another coaster necessarily to replace Big Bad Wolf (I want that one back!). They still have four, and think the park should have another dark ride. Curse of DarkCastle is one of the newer, non-traditional dark rides in the same vein as IOA's Spiderman, and Corkscrew Hill is a 3-D projection with stationary (albeit jumpy) vehicle. Is the day truly past for any new Pirates/Haunted Mansion type dark rides where you, in a small or medium-sized vehicle travel slowly past unfolding scenes of animatronics? I wonder...
I think it's sad you don't mention the British and European parks Blackstone/Merlin own.
