Just got back from a long drive to Disney from WI and I would highly recommend filling up before you enter FL . The prices in GA were about $1.85 - 1.96/gal vs. Florida which will charge you about $2.30-2.40/gal. The cheapest gas in Fl was actually on the Disney grounds - go figure???
The fill-ups I am referring to are just over the GA/FL boarder. We unfortunately needed to fill up and decided to wait until we got into FL. Bad move! Every station off the interstate was at least $2.25/gal and kept getting higher as we went further south. If you need gas on the interstate - fill that tank to the max in GA!!
A few stations in Orlando were better, but the cheapest was still Hess on Disney grounds at $2.02. Lake Buena Vista area comes in around $2.30.
As of Friday, the Hess station off of I4 at Fairbanks Ave was 1.99. I would imagine that if the on property Hess stations have dropped in price , that this one has too!
I know, I think its all about working the stats. They figure a certain number of people buy gas everyday. The days that the most people buy, are probibly the days they will raise the prices.
We always take I-75. We've consistently found the lowest prices in GA at Exit 5. I believe it's a Speedway station. It's just east of I-75 on the north side of the road.
