My girlfriend and I went to St Kitts in July, 2007. We stayed at the Marriott. The accomodations were fantastic. We had an OV room with a wonderful patio area. Beach is large, smooth and clean.
We only ate one meal at the Marriott and it was at Blu. Meal was excellent. Would reccommend it. Most meals we ate around the Marriott area and in town. The Monkey Bar and Turtle Beach are very good. Good breakfast at the Sunset Cafe.
Overall, excellent experience and would go back in a heartbeat.
