★★☆☆☆ App is so unstable it's frustrating. Buttons that were there don't show up, text doesn't show up, etc. I have to wait 1-2 days and then it shows up again. I saw my reservations and check in options, making a mental note to check in later in the day. A few hours later, tada! The check in button is no longer visible (it's just blank now) and all my reservations are not showing up. Get a better app engineer.
