I booked a room at Select Hotel Checkpoint Charlie in Berlin for four nights. The price advertised on Expedia was $85.20. That was what they charged for the first night. For the second night they charged $87.78, but for the last two nights they charged $214.30! When they confirmed the availability of the rooms, I provided my credit card information, not paying attention to the total cost for the four nights, and they claim there is nothing they can do. Of course, I understand that prices for hotel rooms vary from day to day, but $214.30? They claim the price went up (almost 300%) because the hotel was heavily booked, but that is not true. In fact, it was fairly empty... They're not even embarrassed that they charged such an inflated amount.
