Orlando update

Actual Q&A below this, so scroll down! Apparently the Marriott World Center is a great place to meet, and since I don't have a car it's going to be tough for me to get anywhere else. I'm proposing Monday, March 23 at 11 am at the Marriott World Center. But I'm not sure where, as I've never been there. Anyone have a landmark we can meet at? And is that time OK for the people coming with kids?
