We have been in that type of room 3 times. Twice on the Carnival Spirit to the Mexican Riviera. The first time it was fine, but it was also cooler and we had some weather. The next time it was pretty noisy, not from the guest, but from the crew cleaning and rearranging the chair during the ealy morning hour.
On the Hal Zaandam, we weren't in the room, my Aunt was. It was very quiet. This was an Alaskan cruise with cooler weather.
so I think it has to do with weather, and the age of the crowd.
With that said I would and have booked a cabin like that again! We love the location.
