I made a reservation through Travelocity and got a rate of $112 for the night in February 2004. You can get cheaper rates through Hotwire or Priceline. With Hotwire, you look for a hotel near the airport with 3 1/2 stars and no shuttle icon. However, some people did this and got a different hotel than the Hyatt. It seems the hotel left off the shuttle icon to attract more people to book a room there. I didn't want to take the chance of not getting a room at the Hyatt because we will be arriving very late at night, so I chickened out and paid more for the room by booking through Travelocity. I have never tried to book a room through Priceline, but Barb and Tony from CastawayClub.com do it all the time. You should check their website for tips.
Good Luck!
