I would do the research and try to get a room throught Priceline or Hotwire. I think Priceline is cheaper, but with Hotwire you will have a better idea about things upfront. I got the Orlando Marriott Airport location from Hotwire for $50/night for one night last month. I'm sure I could have gotten something (maybe even the same thing) cheaper through Priceline, but at that time I was too squeamish to try. Just do the research and know up front what you are doing at the sites that explain how to --better bidding, and bidding for travel. They are such great helps for this!
Good luck!
BTW, my room at the Marriott was beautiful! There is an indoor/outdoor heated pool, a hot tub, and a kiddie pool as well there. There is also a coffee maker in the room.
