The Dan chain and many other chains worldwide have implemented a new policy which particularly affects prepaid reservations eg group tours. Dan Hotels are sneaky at check-in. They swipe your card as is customary. They don't tell you they are actually charging one or two nights to your card, and they will not tell you or issue a receipt as most credit merchant agreements require. We happened to catch one charge at the filthy Dan Tel Aviv from our bank's web site during our stay. Once home Citi informed us that their King David Hotel in Jerusalem had failed to reverse a $735 charge. If you must stay at a Dan Hotel, also be aware of dirt, and creepy crawly things.
