Believe the reviews!

It takes a lot for me to truly believe negative reviews. I tend to believe that it is just user error or people mad at the company. But most of the other reviewers are right on. This app is nothing short of horrible. It doesnt load most of the time and when it does, it wont find my reservation. I even tried to get it to work loading directly through the Marriott website with my reservation number. Nope. It either wont load or tells me I have no upcoming reservations (which I do, of course.). Dont waste your time.
