Just so you guys know we have added 'lowest rate' clauses in our contracts with the hotels.
Essentially, this means that they have to give us the lowest rate they offer anyone else (including many travel sites or AAA).
Of course some travel sites take a loss in selling rooms, selling it for less than what they paid but making the cost up in other user services. Still if you do see a lower rate for a room than our rate, please take a screencap and let us know.
Of course if our room block is sold out, by all means check for things like AAA rates for rooms outside of our block.
