For a current look at gas prices you can visit
www.orlandogasprices.com and it will show you the lowest and highest in the Orlando metro area. (You'll see that I regularly post prices there.)
In the Disney area the gas stations on State Road 535
south of I-4, just over the border in Osceola County (Kissimmee) are usually very good. The three Hess stations on Disney property are also very fair and sometimes among the lowest.
In the Disney area there are also three stations on State Road 535
north of I-4 that are notorious for ripping tourists off. The worst is the Chevron on 535 right at I-4, further north is a Shell and 7-Eleven/Citgo. Avoid at all costs, please. They may be cheap by UK standards but are outrageous by local standards. There are also some stations off TOLL 528 (Beachline Expressway) near the Airport that are high.
You can normally jam a lot of gasoline into your rental car at cheaper prices near where you are staying and the needle will still show FULL when you return the car at or near the airport.
malibuconlee, when we moved from elsewhere in Florida to the Orlando area a few years ago many of the stations were below $.99/gallon. Thanks to George and his Texas oil buddies, we're now triple that. It's shameful!
