Booked through hotels.com when i had an exepected issue with a hotel my Sister booked. Landed in Vegas with no where to stay at 12am. Site asked if i needed to check-in before 2am. I said, "Yes!" Thought to myself, thank goodness I won't have to be out alone all night since my family wont be in town for longer than expected and they needed the booking CC and ID of the one who rented the room. Get to the hotel and they say "Yeah, it says that online, but you cant check in till 6am." So...had wander the hotel for 5 hours. When I got to my room, there was no hot water, no wash cloths and the whole non-smoking floor smelled like smoke and mildew. My room was at the very end of the hall, in a corner by the stairwell door. Definitely not going to repeat that experience.
