Which resort to try this time?

Hi all!!
My husband and I have been to Couples Negril twice (2005 and 2007) and absolutley loved it!!! We want to plan a trip to another couples resort this summer, but figured we should check out another one of the resorts.
We are thinking of Sans Souci or Tower Isle.
The things we loved about Negril was the swim up bar, the water volleyball, sand volleyball and late night grill with jerk chicken and the pasta restaurant.
Does anyone know if these resorts have water and sand volleyball?
Any other info is also appreciated.

Thanks so much!
Laura
