This happened to me before. I booked a room in Austin at a La Quinta Inn through HotelTonight, and when I showed up the place looked abandoned. Turns out, it had been turned into a homeless shelter, and you couldn't stay there even if you wanted to. There was a big fence around the whole building, those portable chain-link type fences which are used around construction sites. And obviously there was no one working there that could give you a key to a room or anything like that. It was pretty upsetting.
