If we're heading down to WDW, I almost always wait until I get onto the property to get gas at the Hess stations there. They are typically the same or cheaper than what I can find where we live approx. 25 miles away. Also, as was said, it is cheaper to get gas ON Disney property than immediately outside of it on 535 or 192. The price at the Hess stations on WDW property last night (8/4/06) was $2.95/gal.
