In the last six months, my husband and I have been on two cruises. The first, in November, was a RCCL (Odyssey of the Seas) with our youngest daughter and young adult grandaughter. The ship had virtual trampolines, bumper cars and a sky lift that soared above the ship. We all really enjoyed it. In March we went on Celebrity Constellation with our older daughter and some friends. We all really enjoyed that one too. But when I described this latter cruise to our younger daughter, her response was "That sounds really boring". So I guess it depends on what you enjoy doing onboard.
