My wife and I just returned from CTI (Close to SS). We loved going to Dunn's River Falls (free) and really loved Mystic Mountain. chairlift to the top of the Mountain and the Bobsled run was fantastic!!
CSA is heaven on earth. You are going to love it. Make sure to go to the Martini Bar one evening and definitely go snorkeling. And mostly just enjoy each other as you relax on the most beautiful beach you will ever see. CSA ROCKS!!!!
