When you get off the tram at Serenity Bay, the cabana check-in booth is right there. The cabana host will take you in a golf cart to your cabana and show you around.
There is a closet where you can stash your stuff, including a small safe for any valuables.
There is a basket full of clean beach towels, so you don't need to bring any from the ship.
There is a small fridge that is stocked with sodas, fruit, and cold towels. On the counter above the fridge is a small basket with snacks (chips and granola bars, usually). Next to that, there is a button on the wall that you push when you want your cabana host to come around to take you to lunch or the tram stop, or when you want to place a drink order.
In one corner of the cabana, there is a curtain you can pull around yourself if you need some privacy to change in and out of your swimwear.
You have several chairs and loungers, both inside the cabana, where there is a fan to help cool things off, and on the deck. There is also a small basket containing bottles of SPF50 sunscreen.
Next to the deck will be a couple inner tubes and floating mats. There is a shower that you can use to clean off after you've been on the beach or in the water. And there is a hammock to relax in.
When you want to go to lunch, you can either walk (about 5 minutes) or you can call for your host to come pick you up. The same goes when you want to go to the tram stop. We have found that if you wait until the very end of the day, you can hitch a ride with the cabana host all the way back to the ship and skip the trams altogether.
The cabanas are our favorite way to spend the day on Castaway Cay. You will have a wonderful time!
