The off season prices are not bad at all either. The villa can sleep 8 comfortably and privately. Two in each bedroom and two more in the living room. The living room is just as private as any of the bedrooms because of the open air halls and self-contained living areas. Hard to imagine, but you're in Raleigh.
Peak season is about double that rate still a good deal really.
Airfare, food, and everything else are extra. There are plenty of other villas and resorts there too, but I don't know anything about them. The web sites at the end of this article should help you. The restaurants will blow your mind. They are expensive though.
