If the Rules of Disney Tourism are to be believed and adhered to, you've picked a decent time to go, as you'll be leaving just as much of the Thanksgiving traffic is coming. I would suggest, if you could move it up just a few days, like from 11/10 through the 18th. THis way, you're only dealing with one weekend instead of two, which is when all the tourists AND locals will be around, and there would be even fewer early THanksgiving travelers.
