Castaway Cay was our only stop on this 3-night cruise, and the island is absolutely beautiful. Disney has done a remarkable job of laying out the island in such a way that everyone - old and young - can enjoy their time here. Since we were not traveling with kids, we took the tram straight to Serenity Bay, the adults-only side of the island. While I usually seek out the shade on a hot tropical day, it was sunny but chilly on this mid-January morning in the Bahamas, and I chose to worship the sun instead. The beach was absolutely beautiful and not very crowded. It is located a good distance away from the family and kids section - so much so, that it was easy to forget that there were 1,000+ kids on the ship on this particular holiday weekend. The complimentary BBQ was good and fulfilling, and after lunch we got back on the tram back to Pelican Point. This is the side of the island where it's all happening - the family areas, beach toys, water slides, snorkeling, bike rentals, and everything else a kid would love. If you're looking for a beach day on your Disney cruise, this would be it - don't miss it!
