Garbage – MGM Rewards Review

Booked through a 3rd party site which makes mobile checkin on this app impossible. Wasn't made aware that 3rd party checkin isn't available on this until after I waited in line for too long and was told I 'didn't have to wait anymore if I had the app'. I tried the app, didn't work. Back in line, at the back of the line. Stay is not off to good start.
