For as long as I can remember, you NEVER, bought gas on WDW property because it was sooooo much more expensive. Then Hess took over and I was shocked to see the price was in line with offsite gas stations. We now fill up at WDW.

Who would have thunk it!
On our last trip to WDW we drove down and would not get to AKV until 10:00pm. We got a bit lucky when we stopped for food at BK. I could drive from the BK parking lot to a gas station lot just feet away. We were going to eat in the car to save time so I dropped the family off at BK while I went to the gas station. Then I noticed the price.

The price was much higher than it should have been, maybe 25 cents a gallon. Normally there is no way I would pay that price but to take the time to tell the wife I was going to a different station, fill up and return was not worth the extra $4-5 I paid for the tank of fuel.
Many years ago I was driving in the NC mountains on the Blue Ridge parkway. I used up more gas than I thought so I had to pull off the parkway to find fuel. The parkway, even today can be and usually is fairly remote from services. I went to the little town that was closest to the parkway but it still was 10-20 miles away. I got into this little valley that had an even smaller town with a few houses, a fish farm, and a gas station.
The gas station had a large sign up on the front of the store. The words were to the effect that the gas was priced as high as the law would allow. It was something like 50% higher than what you would pay anywhere else.

Given the choice of running out of gas or paying the price I paid up. It sure beat the alternative.
I have always wondered if the locals had to pay the price as well.
Orlando should make the gas stations put up signs to post the prices though I bet it would not make much of a difference. In the end you do have a choice. Sometimes it might not be a good choice. Pay the price or miss a flight. Do not pay, run out of gas, and call for a tow in the middle of now where after finding a house with a phone.
Last time we rented a car the rental company would charge us a fortune to fill up the car that was not returned with a full tank. THAT was a rip off.
Sometimes gas is just plain cheap even when it is outrageously priced.
