We did a Royal Caribbean cruise to the Bahamas and there were very FEW kids. (Our 9 month old daughter was ONE of three young kids that we saw!) Totally laid back and relaxing type cruise.
Then we did Carnival. PARTY SHIP ALL THE WAY. KIDS EVERYWHERE. (We had 2 small kids with this time.) But the ship was PACKED with kids and families. And yet, somehow, it was still a total drinking party........? We HATED IT!
I do know I read about a cruise line that is ADULTS ONLY when we were searching for our trips. Google it. And we booked it ourselves to save money.......
