According to Marriott, rooms booked via Kayak are only available till 10am. At 9:45am, some brute knocked on the door like a police raid. I’ve never been so insulted. They also opened the door and started walking around! At 9:45am!!! No recourse, no nothing. As a Platinum Elite level Marriott member, I expect more. And shame on Kayak for burying this in small print. The room and building were atrocious.
