We did the Horizon, in April 2022, and had cabin 5218, we LOVED it. We didn't hear any noise from the bar area. Granted we spent a lot of time there at night. We loved being on deck 5 and how close it was to a lot of activities we like to do like trivia, and the coffee shop is so close. I would definitely book this cab again.
The Havana Pool area is great, by the end of the cruise you will make new friends.
Have fun!!
