For me, it’s all about the wine cost. If you normally have three $22 glasses a day, it’s probably worth it. If you normally drink beer or cocktails, maybe not.
I think a lot also can depend on the length of the cruise. We just had a 4 night leg between two14 day itineraries on a B2B2B The $80 each value was there just for the two specialty dinners if that’s something you might want to do. For that cruise, we’d have been crazy not to get it
