Do the tolls. Less crowded roads and better condition. It's vacation after all.
BTW, if you haven't already, spend a few hours looking over this web site;

Excellent info on crowds and what and where to go using past data.
Also, if you don't know how to use fastpass, learn. Will save you a bunch of standing in lines.
Take time to enjoy Disneyworld. Take the boat across to the magic kingdom at least on one of the days.
Food isn't that bad of a price in the parks for lunch. Maybe $10 per person. Much better than hauling food around all day. Make your reservations and it's even better
Went with the grand kids last spring and I already want to go back! Disneyworld is huge. If you are having crowd issues, then just go to some other part of the park(s). There really isn't a bad place to spend time there.
