I used 2 Premium Pounds during my stay at the Redmond, WA Marriott for an exchange rate of $200.96 per 100 pound certificate. I tried to argue that the person had the wrong rate and it should be in the range of $188ish as I did not want hassels later on. Well when she insisted that she had just called "Marriott Corporate accounting" and thats the exchange rate she was given, I said I'll take the extra $11 or so. I hope this person does not get in trouble for this later on.
