We visited "Couples San Souci Resort" in Ocho Rios when we visited there. It is a couples only all inclusive resort. The cost was $100 for the wife and me and the cab fare was $20.00 round trip.
We really enjoyed the resort. 2 beaches, 1 regular beach and 1 Au-Natural as well as wind surfing, paddle boats and the like. I highly recommend this resort...oh yeah, no kids on the beach, adults only resort!
