I have been using gov't rate everywhere I travel for the past 18 years. Only one time did I have trouble - at the Marriott Delray Beach March 2005, I booked on line, govt rate when I got there they said I had to put it on my govt credit card - I had printed the entire confirmation and reservation and NO WHERE did it say that.....when I got home from our trip - I looked at their website and that hotel had indeed added it. So its my fault if someone is trying to get a $400 room, in season for $150. So this year we will just go a little later not during high season....
