On our first cruise when DD was 4...there was a family of five with another 4 yr old girl. They became friends, and were together throughout the cruise. On our last cruise when DD was 5 we were seated with a family with a 5 yr old boy.(unfortunately our DD was hoping to be seated with another girl). The family decided they wanted late seating. The following night...MAGIC!!!...twin 6 y.o. girls were seated with us(of course with their parents). The three girls had a wonderful cruise, and still contact each other from time to time.
