When are you headed down?
We will be there for Halloween week somewhere in the 700 loop.
From Wilmington it takes us about 16 hours of driving + 2 fuel stops to the FW gate.
We leave very early in the morning and stop at the welcome to Florida rest area (about 12 hrs + any stops). There is a very large camper parking area at this one , get a few hours of sleep have some free OJ in the morning, get some Disney brocures (SP) for the kids and finish the drive in the morning. we usually arriving before check in time so I park in the overflow lot, head to Trails-End for lunch. pick out my site from the empty ones on the way back to check in. This works most of the time I get the site I want
As far as to long for the kids. Get a 12v dvd player (Wal-Mart has them with 2 screens very inexpensive)and bring lots of dvd's. if they have game-boys, PSP or something get them each a new game but don't give them out untill you are at least 2/3 of the way there.
They won't be nearly as tired as you are.
On the way home we are stopping at the South Petersburg Va KOA again 12 hrs from the FW gate.
