My question is that my husband and I are expecting to go on a cruise on the Disney Fantasy (maybe?) January 2019... are there things to keep childless adults as entertained on say a Carnival cruise? I'm actually really excited for Star Wars Day- we're big Star Wars fans, but other than that is there activities? Preferrably that don't cost extra? And would we be creepers if we went to things geared children? I've been on RCC and CCL multiple times and this will be our very first trip aboard a Disney Cruise.
We have cruised DCL a few times minus DD and were always pretty busy between the entertainment and just the ship in general. The comedy on DCL is of course clean even for the adults which is fine, and of course the entertainers are hit or miss depending on your tastes. We did do the rainforest room on the Fantasy and used it quite a bit, it was a nice way to relax. The one surprising thing though was how quite the piano bars are at night even with a really good performer, maybe only one or two people show up. I can't fairly compare it to RCCL, because on our trip there were very few kids so the late night activities were very well attended. Had there been more kids on the cruise, not sure if as many adults would have been out at the late night activities.
