The app is helpful, and it does appear to be working better than when I (tried) to use it on my trip. The was very buggy when I was in the parks, and the wifi was okay, at best. At the resort it was fine, but it the parks it was slow. Hopefully they have been making improvements and everything will work well for your trip! The technology does have the potential to be really cool, I'm just not a fan of the limitations that come with it, and the inconsistency of it's functionality.
