So I book two hotel rooms through Starwood Preferred Guest - SPG and when I got to the hotel they said they only had one reservation for one night on file. I booked one of those rooms for 5 nights. When I called their customer service all they said was basically oops, that happens sometimes but since you managed to find another hotel room then everything is fine right? Wow....just wow. So since apparently that happens sometimes and apparently they cannot guarantee that when you make a reservation through them that the hotel will in fact have your reservation in their systems, I would strongly suggest to people to NOT use them since you may not have a hotel room when you arrive to your destination.
