Coco Cay is Royal Caribbean's private island, so that's a beach day with beach type excursions, such as snorkeling, parasailing, etc. They also have floating beach mats that you can buy for the day, for a very reasonable price.
I'll be on the Freedom in October, and can't wait! This vacation can't come soon enough!
