The kids quickly learned the layout of the ship faster than we did and each of them had a room key in their lanyards, so they could come as go as they needed. They loved roaming the ship as a group, playing hide and seek everywhere and exploring. There were designated kid clubs for them to hang out in but they never did too much of that, choosing instead to explore and enjoy not having to be supervised all of the time. It made picture taking challenging because I just couldn't FIND the kids a good portion of the time.
It didn't take long before we found ourselves among some beautiful scenery, and sometimes as a kid or two ran by I managed a photo of them.
Another advantage to a Disney cruise, characters, all over the place. The girls love meeting characters and through the week they met some every day.
