This is probably the best park app (besides Disney). Its very easy to use, loads fast, doesnt drain your battery TOO much, and never glitches or lags. The information is up to date and the new map feature is great. I also love how I can use my phone as a pass, as its one less thing to worry about.
However, there is one problem that holds this back from 5 stars: the wait time feature. This is always wrong (and I rely heavily on it). It frequently says rides are down when they arent, and the wait times are 90% of the time inaccurate. For instance, saying one ride had a 55 minute wait when in reality it took 5 minutes, or vice versa saying a ride had a 30 minute wait when I waited in line for around an hour. This needs to be fixed, as it is a really important feature of the app. But otherwise its great.
