I was lucky enough the go on the maiden voyage of the Disney Wish.  It is beautiful!  While there are a lot of amazing things to do for all ages on the ship, they do have plenty of adult only spaces.  ​

The Bayou is on Deck 3 and is the main bar.  It has a New Orleans theme and has live music.  The Hurricane is their signature drink. 
Nightingales is also on deck 3 and is very close to the Grand Hall.  It is themed after Cinderella.  It has a grand piano and live music.  A fun drink to try there is the Ice Bubbles Cocktail.  Your cocktail comes in an ice ball and they give you a little hammer to break it open.  
Also on Deck 3 is the Hyperspace Lounge.   This is a fully immersive Star Wars experience.  They have a fun drink menus with collectible cups you can purchase. You need a reservation to get in.  
Keg and Compass is on deck 5.  It is the sports bar on the ship.  It is a nautical themed pub.  It is beautiful.  The wood carvings are amazing.  They do have a menu for food that is not included in the cruise fare. 
The Rose is on deck 12 outside of Palo and Enchante.   The view is amazing.  It has floor to ceiling windows. Free The bar is very elegant.  You can find a very extensive wine list and signature cocktails. 
Deck 12 also has the quiet cove pool area.  Adults only.  It is in the back of the ship and no kids need to walk back there.  Unlike the other ships, where kids were able to walk through the adults sections.  There is a bar and the quiet cove cafe.  
There is a secret bourbon bar in Hook's Barbary where you can get a smoked old fashioned!
