I also spotted a 6' nurse shark. Caneel bay also offers rafts so you can lazily float away on the water. The snorkelling, rafts are all complimentary, as are sailboards, kayaks and sunfish sailboats. For dinner, its somewhat dressy, i.e. very few people in jeans. Long pants required at night - in winter season, a dress jacket also required.
Ladies can wear sun dresses or the like.
Its an upscale sort of place but in a pleasant way - so you need to dress nice but not in an elegant way. No flashy jewelry. The resort offers a variety of meal plans. The day starts with Dinner and ends at lunch the next day. Food was very good and with a good selection all around.
