We are in our 60's. We've cruised on carnival and NCL, we like both but can get more for our money on carnival. We don't mind the kids, it reminds us that we are alive!! We don't drink a lot but we still enjoy setting in the bar or the casino. We were on one ship that every one was in bed by 9:00/10:00... how boring! Liked the food on NCL more, but we like the steakhouses on carnival more than the buffet. We've never seen a fight on a cruise, but I'm sure that'll happen eventually. Guess it's what you want out of a vacation/cruise or what you make it. And Happy 40th Anniversary to you both!!!
