The numbers on the app map dont match those on the Disney map; they should as it makes it easy for one person looking at the iPhone to quickly exchange notes with a person looking at a paper map. Also, the El Pirata Y el Perico Restaurante in Adventureland no longer sells Mexican food but BBQ pork and burgers instead. It would be useful if there were some way for a user to indicate rides that are to be done/have been done/arent interested in doing, sort of a checklist. And could the updates indicate which rides are down for maintenance (Splash Mountain as of 13 Feb 09) or will be (Space Mountain soon).
It would be awesome if there were a real-time line wait indicator, but I doubt that even Disney has that centrally available.
