I was there on an awards stay in Jan. I was allowed to update to Club 91 after I got my confirmation from Marriott. As I made my reservation well in advance, the rate was $80.00 per night. When I got there they tried to charge $90.00, but honored the original $80.00. The rate included the upgraded room, all on the 14th floor, and club privileges for up to four. I believe all rooms would be considered ocean view, these rooms had a larger balcany which was of limited value since it still had only a small table and 2 very uncomfortable chairs. If you do upgrade, when you arrive ask for a room on the north side if possible at check in as this side overlooks the main pools. I did not, but if you do upgrade, I would ask the Club 91 people if better balcony furniture is available, especially since there will be 4 of you. The upgraded room and free breakfast alone will pay for your upgrade, and the rest will be gravy.
