As already noted, a reduced rate for 3-4 hours is unlikely. However, you might want to look at Priceline for a cheap room. Depending on time of year/day of the week, perhaps $50 or less.

The likely Priceline awards can be found at http://biddingfortravel.yuku.com/top...SKA-HOTEL-LIST, and Bidding for Travel can offer suggestions on getting the best rate. Note that the moderators can come off as somewhat brusk (especially if you don't read the instructions before posting), but they are helpful.
