Quiet Cove Pool
Yes, Disney ships have a dedicated adults-only pool area on deck called Quiet Cove. In this area you can escape the loud, splashy children's areas and relax in a kid-free hot tub! Just off of the Quiet Cove pool area is Cove Cafe serving specialty coffees and treats like pastries and cakes. They also have magazines to read while relaxing in the comfortable environment.
On Castaway Cay, the private island, there is a dedicated adults-only beach to escape to with hammocks, beach chairs, and umbrellas for no extra charge. Not interested in laying in the sun? Try a massage in a beach-side cabana!
After Hours District
We had the opportunity to join a private mixology class on the ship for $20 per person. They offer public ones as well, you have to look for the information in the Navigator and sign up in advance. We aren't big drinkers, but we thought it would be fun to try! The class lasted nearly two hours. Alejandro taught us how to make 6 different drinks that they serve in the bars and lounges on the ship. We ended up enjoy one drink more than others, the Caipirinha. So much so that I went out and bought Cachasa and a muddler once we returned home! The final drink of the class was a layered drink- we were not a fan, but it was a fun drink because the bartender told us we could not use our hands to lift the glass!
