I've kvetched before about searching for the government rate on Hyatt.com. But this is a new one for me. First, by "government rate", I refer to the maximum reimbursable rate for official government travel. The General Services Administration sets these rates for the 48 states (DOD sets AK & HI), and they vary according to destination and month of the year. No hotel is ever required to make a single room available at this set rate - simply, if that amount is advantageous, it is at their option to offer it. Hyatt.com provides a button one may click to search for the "a" government rate, and I have found it to identify rooms at the reimbursable rate maybe 75% of the time. Often what purports to be a government rate exceeds the reimbursable rate. I will not delve into semantics, but I submit that the term "government rate" is understood in the industry to be the GSA reimbursable rate and not some sort of a discount. Some people - often those who are not government travelers - disagree. Lately, I've been noticing that hyatt.com is doing a poor job adjusting for seasonal fluctuations. One property in Boston I've stayed at keeps offering a December federal rate of $221, when that federal rate (as defined above) declines to $158. ($221 is correct for October, however). It seems that they want to get it right, but, somehow, at times cannot load the system to account for seasonal fluctuations. Yes, it is the federal traveler's responsibility to verify that what purports to be a government rate is indeed reimbursable, and the federal traveler eats any difference out of pocket, but some help would be appreciated. Just now, I encountered something completely new. I tried to book the Hyatt Regency Chicago for 11/13-14. It offered a state government rate of $130, which I suppose is the Illinois state government rate for that period. No federal government rate was available despite the federal reimbursable rate being $190. I went so far as to call the property to inquire about getting a room at the federal government rate, but no luck. The agent explained that they make only a limited number of rooms available at the federal government rate. To provide points of reference, the current "Hyatt Daily Rate" is $279, the "Winter Sale Rate" is $195.30, and the "AAA rate" is $251.20. As a very crude rule of thumb, I have found that Hyatts and Marriotts generally will make the federal government rate available when that rate is 2/3 of the basic internet rate for the night in question. (That is, they want the basic internet rate, but will settle for 2/3 of it, lest a room end up unoccupied. This is the first time I've heard that the federal rate is capacity controlled by any property - rather, in my experience, properties will make unlimited rooms available at the government rate so long as that rate is advantageous for the night in question. Another very odd phenomenon has recently arisen - I've researched government rate availability at some properties, and the ONLY room types for which there is availability are the ADA compliant rooms. I've never completed such a booking, but would feel very odd doing so when I do not need an ADA compliant room. Again, they may choose what they offer. Oh, one more bit of advice for federal travelers - your searches are more likely to yield accurate reimbursable rates if you enter 81538 as the corporate/group number - that is the "Fedrooms" rate. NONE of this should be interpreted as suggesting any entitlement to a room anywhere at a fixed rate. Its a free market, after all. It just recounts my own most recent experiences and frustrations. I've booked at the Marriott Magnificent Mile.
