$50/person for Renaissance Island if you are not a guest of the hotel (in 2004). Don't know if it includes food or beverages, but I don't think so. We decided to pass. I hear there's great snorkeling there so we'll probably go next year.

Went to DePalm Island in May and loved it! Fabulous snorkeling. Do buy a disposable underwater camera. They provide snorkeling equipment, however, we brought our own. You have several options. We chose all day + food & beverages at about $85/person. Additional $10 or so if they pick you up from your hotel. Other options were 1/2 day w/food & beverages and 1/2 day w/o food/bev. There may be others.
