Ed,
Remember that night, I was solo.
I dumped my dad with my sister for the night. I told her it was her turn. After all, he was her birthday gift, she should enjoy his presence as much as I did.
And my son was at DisneyQuest from 6 p.m. until I picked him up at 12. He wanted to stay longer, but they were locking up and tossed him out.
So if you bring family, make sure you have a place you can dump them for the meet. Peggie
