I know they cannot guarantee all requests but we usually give a few room numbers that we like and have always gotten one of them. The deluxe rooms are hard to call though as far as what is the best view. The problem is that the ground floors can have things such as beach beds, the big gazebo, tree trunks, etc... that block your view depending on the room but the top floors usually have palm trees that at least partially block your view as well. The absolute best view in our opinion is either the Northern most building (I think 25) ground floor center.
or the buiilding just South of the new suite/North of the Passion Suites (14 I think) upstairs. We are total beach/ocean view whores and love watching the sun rises so I understand why this is important to some people whereas others treat it more like Vegas and say they only go to there rooms to sleep. Good luck!
