Hyatt is having their monthly 48 hour sale where you can save 15% to 30% off of best available rates (BAR). Sometimes you can save quite a bit of money and sometimes you cannot. These rates are valid at US, Canada, and Caribbean hotels.
Sometimes it is actually better to book an AAA rate that might include some extras like a complimentary breakfast. AAA rates are also normally not prepaid and cancelable.
