And remember you need to be at the bus stop, ready to go, 15 minutes before the time you are assigned. Buses do come early, and if you are not there will leave without you. Then you have to find your own way to the airport. My dad almost missed his early morning ADR bus before, as I didn't tell him that.
Thanks! We are coming back from DCL and I thought we might do one night before we went home but I think we might skip and just go home after the cruise. Don't think DH and DS would be happy to be up that early.
