We were on MSC Seaside Yacht Club in a balcony room and it was really nice. The sitting area was big with a full-size sofa and the balcony was larger than normal as well. Probably could've fit a lounger in there but they only placed chairs and a table. We did spend some time in the room and on the balcony, so thought the price was worth it. Also, had views of their private island for 2 days and that view can't be beat. I like that the yacht club area was all in one place. We did leave it to check out the buffet and shows but you really don't have to if you don't want to. For MSC, we will probably only cruise the yacht club only. I haven't done celebrity yet but it seems nice too. I don't have any loyalty yet since I just started cruising a year ago so I appreciate this comparison post!
