It is a little embarrassing when you are told that your purchase on your room key is turned down. They do not inform you that they set some arbitrary limit that has nothing to do with your credit card limit. I visited the front desk and got my limit upped. It was a good thing I had my credit card last night with me in HP or after standing in lines to both enter the shop and then to get to the register, I would have had to put my purchases back.
