If you are driving down, make sure you fill up in Georgia before hitting the Florida line. Also, if you have a BJ's or Sam's card, both of those have gas stations and their rates are usually lower than other stations. If you are only having a short trip, it may not be worth it to drive out to the BJ's or Sam's. I also second the HESS onsite stations. They were re-opening end of May, early June and their rates were very comparable, especially considering the convenience.
