Hi there,
We were at WDW a few weeks ago a noticed that the price at the local Hess Gas Stations were around $2.70 per gallon. You may not be aware that the US Gallon is equal to 3.75 litres as against the UK Gallon which is equal to 4.54 litres. At WDW gas stations can be located at the following areas: Outside the Pleasure Island/Downtown Disney area, Near the Boardwalk hotel across from the MGM parking access road. Another is located near the Magic Kingdom Car Care centre and is the best place to fill up on the way out of the MK. Other stations are available outside WDW near the Crossroads shopping area. Hope this helps.
