I pack a cooler with drinks and fruit, and then a whole duffle bag of snacks.
We will stop for breakfast at a Cracker Barrel in the FL panhandle. CB is one of the few restaurants my DS6 likes. They are all over, they all look the same, and have the same menu(including pancakes and grilled cheese, 2 things on the short list of things he will actually eat!).
Then stop for an early lunch, usually fast food, about 3 hours outside of WDW.
I like to stop at the state border rest areas to take pictures, stretch legs, etc. DH makes fun of me because one year I stopped at the LA/MS border, which is about an hour into our driving...
We got our Disney Vacation Planning Video this weekend! DH and I watched the MK, Epcot, and HS sections.
I do agree that once the ADRs are made, except for paying off the trip, I feel a lull in my planning!
