If you go out the north exit of the airport scrounging for gas, take a left at the first light. Next light, just over a mile west, take a left and just ahead on the right is a reasonably cheap gas station (the same one I mentioned six inches above).
This route is also quite suitable for going to Disney, you get on 528 west just opposite that gas station and take 528 all the way to I-4 west. Just 75 cents for tolls.
