Well aware experiencing something in person is different from viewing it online - that's why I have yet to post any comments on Tiana's until I ride it myself this Friday. From Dave Cobb's video on YouTube, that does an excellent job at capturing most of it in detail, shows me the preview center did it's best at highlight the park's experiences... and that this was something "in addition" to USF, not a new attraction at the back of the park.
Yes, the preview center was part of the marketing package for IOA, I was simply defending it from a comment that had mentioned it as "being bad" and part of IOA's initial failure. Sure it had an impact, but it was so immaterial compared to the Escape-related promos that were plastered nationwide. Preview Center did it's best at showcasing (along with models) each land and details of the rest of the resort (w/ the giant resort-wide model) and CityWalk.
