I guess it depends on what you are looking for and enjoy. We just got off Beyond. Yes it’s a beautiful ship but by the end we prefer the S class, then M. The ship was at capacity and felt very crowded.
We didn’t like the martini bar, missed the alcoves and space. We felt everyone was on top of each other.
The 4 main dining rooms were very nice and food was good but you don’t have the same wait staff so that interaction and getting to know the staff, which we enjoy, wasn’t part of the experience.
The balcony furniture in the SV was not comfortable at all so sitting out there was not as enjoyable as it could have been.
Again, we had a wonderful cruise, it’s hard not to, but I'm very happy our next 2 are on the Silhouette.
