Do not buy

In a nutshell: dont buy this app. I rationalized that spending a lot of money in hotel and park tickets deserved a good app to navigate me around. Wrong. The app does not live up to its promise. the GPS is inaccurate most of the time, the waiting time was always completely off. In the end, the old paper map was far better than the app. If you still feel you need an app, try one that is free.
