Matty--
You sound like a fun guy! I too, get very happy when I get to talk to anyone about our Magic cruise. Only 94 days to go!!
I agree with a lot of what has been said by Roberta and Matt. Our kids had dinner with us every night on last year's magic cruise, but were pretty free during the day. DS7 was in the clubs a lot or with our friends that we were traveling with. Our DD12 hung out with her friends most of the time, but we all had dinner together. Often the kids left before dessert, either to meet up with friends (DD) or to go to some activity at the OC (DD). Dinner really was a great time for us all to catch up, and we definitely spent most of our port days together, unless DD was hanging out with friends at the beach. DS had a reasonable "vacation week bedtime"--around 10:30 or 11:00pm. DD usually was in by 1:00, especially if she and her friends went to a late movie.
