I'd agree with the Sun Pass that pre-pays your toll road use. We purchased one last winter at a Publix grocery store and preloaded $30 on it for some trips down to Tampa. The pass is well worth it because you avoid lots and lots of stoplights, traffic, and other things that slow your travel. We purchased one that sticks in the window of our pick up and can only be used in that vehicle. There is another pass that can be moved from vehicle to vehicle, but that one is more expensive. Info on the Sun Pass is below.
