I'm fairly tech savvy, and this app always gives me a headache. It's poorly designed and not user friendly at all. Besides, it requires its users to be on it the whole time rather than living in the moment, enjoying time with friends and family at WDW. I wish that I didn't have to use MDE at all, but Disney has made it indispensable, and that is just one more reason I'll come back less and less in the future.
