Castaway Cay: Do the Castaway Cay 5K! It will help burn off the calories from all the food you have ingested after being on the ship for 3 days. We booked the Extreme getaway package, which includes the sting ray experience, bike rental, tube rentals, and snorkeling gear. You will need the snorkel gear to see the underwater Mickey Mouse statue. There were 3 life guard posts on the snorkeling area. One by the entrance and 2 by the far end. Mickey will be between the 2 life guard posts at the farther end, the second buoy from the left post when we went snorkeling. You can claim the bike and floating tube at Serenity Bay, but the sting ray and snorkeling area is at the Castaway family beach area, so be prepared to share the water with kids.
The family beach was filled with people. There were lines at the buffet area. But that is also where the Disney activities were being held. We opted to go to Serenity Bay, which is accessible by either tram or bike. You can tell it was an adult-only beach because of the peacefulness, stark contrast to the chaotic kid-infested family beaches. We spotted a sting ray and some fishes , thanks to the calmer water.
