Hi - Stayed at Dble tree and Hilton probably 40-50 times in last 4 years. Hilton is far superior, all double tree rooms are the same narrow size and a much poorer view. Hilton has very few poorly located rooms. The residences are not attached to the Hilton and dont really have the feel of the rooms. as they are appartments. If only 2 of you stick with Hilton. Come bcak to us if you need more answers, rgds Andrew
