Bookinhotels.com is a FRAUD. They take you money as soon as you book a hotelroom but don't forward the booking to the hotel. Then after a while they send you a mail that your booking has been cancelled due to 'financial issues'. I checked with the hotel and they had never even received my booking! Now I'm still waiting for my refund.
Also: after my booking someone tried to charge 550 dollars from my credit card. Coincidence? I think not. I reported this to my credit card company and they're investigating it as credit card fraud.
Do not trust bookinhotels.com!
