My 13 DD and 17 DS checked out the kids stuff, and stayed with us, like they did on our HAL cruise.
But, this was a family vacation, a time for us to be our kids friends, not mom and dad for a week.
We did the HAL cruise in June 2002, and it blew our kids minds to hang with mom and dad as friends, they loved it. Found out the old folks can be a lot of fun. So they expected the same on our NYE 2003-04 Eastern on the Magic.
However, we did spend more time in the cabin than expected, since we got upgraded to one with a Verandah. Verandah's rock, but I don't think I would pay the $1,600 extra for it.
