Obviously it depends when you intend to go, but I found a hotel for $74 on this site ([URL="http://search.hotelpepper.com/SearchResults.aspx?fileName=Dubai&languageCode=EN& checkin=2008-02-25&checkout=2008-02-27¤cyCode=USD&sort=MinRate-asc&tabId=0"]hotelpepper.com) And the most expensive was $1500! The choice is yours

Good luck
