I booked my stay at the Sheraton Four Points LAX via Orbitz and was charged twice - once by Orbitz and once by Sheraton Four Points LAX. When I called Orbitz to notify them of the error, Orbitz informed me that the Sheraton reported that I was charged $300 for a cigarette burn to a duvet (I don't smoke, and had booked a non-smoking room.) Nothing was said to me about this charge upon check out, and indeed the room was in perfect order when I left it. I have notified my credit card company of the fraudulent charge, but my credit card company says it may take 45 days to dispute the charge.
I would seriously advise staying somewhere else.
