After having made a reservation through Bookinhotels.com at the Budapest Hilton I became suspicious. I faxed the hotel subsequently and they confirmed that they were holding no reservation for me, had no dealings with Bookinhotels.com and would not honour their voucher . Fortunately I was able to make another booking at just about the same rate via another website, but this time secure and safe as it was confirmed directly by the hotel.
If you use Bookinhotels.com they will debit your card immediately for the full amount and in spite of their cancellation policy it is doubtful that you will ever get a refund.Contacting them is almost immpossible, they never respond. So beware and avoid this website at all costs.
