We like the shows on probably a bigger scale than seems to be offered on Oceania, different bars/clubs, the GF likes to dance but I really don't, I suppose a broader array of venues. We like some of the MSC ships that have a Sky Lounge up high, overlooking the pool, with a band playing jazz or popular hits while we sip Grand Marnier in a snifter or a good red wine.
I've always preferred the mid-sized ships, maybe 2,500ish in capacity. I think the GF likes some of the Monster of the Seas type vessels, since they have so many varied types of entertainment.
That said, I'll probably still give it a shot. We have zero sea days, so between visiting the ports, getting back to the room, relaxing a bit, cleaning up for dinner and actually doing dinner, I'm not sure there will be a ton of down time anyway.
As I mentioned earlier, if she gripes she gripes. At least I'll be providing the cruise, air and hotel.
