If you map out your routes in advance (googlemaps or mapquest and the like) its very possible to route yourself around toll roads, I did this on our January trip. It did take slightly longer since you will hit more stop lights, but I personally thinks its totally worth the time to save the bucks on tolls. Also to get from HRH to WDW you will not hit any toll roads anyway, just take
I-4W. AM traffic was a bit heavy, I didn''t find it as bad as the AM rush hour at home, besides it will mostly be over by 8 or so. Good luck and have fun.
