All four of the resorts have activities staff and the days are filled with activities that you can or can not do, just depends on how active you want to be. All resorts offer the same water activities except CSS does not offer the catamaran cruise.
All the resorts have evening entertainment that lasts to around 10:30pm and then the entertainment moves to the Piano Bar and that bar closes when the last person leaves.
What else are you looking for in your vacation. You've made an excellent choice in choosing Couples and you won't go wrong with any of them. Take a look at each of the resorts and scan all of the pictures. Eventually one will stand out to you (or as we say on the board "sing to you") choose that resort.
If you do have other specific questions about the different resorts, I'd be happy to answer those.
