These shows are pretty good (I love Zack & Cody) but I do wonder if ride/attraction for these shows would be a worthwhile investment. Very limited International appeal for one (not a lot of folk have Disney Channel), and obviously you are using real folk here. Would they sign the disclaimer to have their image used? Lizzie McGuire for example is a show that is no longer in production, so how much of a life span is it going to have beyond now? Not to put a downer on your neat idea, but I can see why it perhaps wouldn't be a possibility. However, if High School Musical has a good international debut (it's about to launch abroad) it would be totally feasible (I think) to have some sort of show connected to it. I know there are talks for a travelling show, so who's to say it might not turn up at WDW?
Disney Channel not represented?? Lilo and Stitch people!!
