We initially booked this cruise based on the itinerary. As this was a first trip to Europe, the port cities, including Barcelona, Genoa, Rome, and Palma de Mallorca, were enticing. I initially booked an ocean view room, but as I researched further, we rebooked in the Yacht Club due to the extra's they throw in (unlimited drinks, wifi package, butler service, priority embarkation and disembarkation, etc), and boy, what a great decision this ended up being.
Yacht Club itself was fantastic. It is SO quiet in that part of the ship. We would be in the Topsail Lounge every afternoon for a couple of hours, and oftentimes we were the only guests in there. The staff is incredibly helpful. The occasions when we would leave that area to go to another part of the ship (to see a show or go to a specialty restaurant, for example) were a shock to they system. The rest of the ship seemed overwhelmingly crowded compared to the Yacht Club.
If you are considering Yacht Club, don't sleep on the following benefits, which were our favorites:
This was a Yacht Club inside cabin. Very spacious for an inside cabin, but not surprisingly for cruising, the shower was very small. We dealt with it.
