I stay in Miami, me and my group of 14 will be leaving on the 25th also it takes us 3.5 hours to get there also. I really dont see how people do it driving 12-16 hours .Maybe we will see each other on the turnpike. Look out for 2 SUV saying disney here we come on the window.
Another vote for July 23-29th. We are staying at WL. First trip for everyone in my party, myself, DH, DD (6 turning 7 at MK on July 25) and my in-laws.
