Living in New England, I have no real experience with any of these stations, but as long as the station by The Boardwalk stays open, with affordable gas prices, I'll be happy.
"Funny" story about the Hess station near The Boardwalk. We were in WDW in October 2012, staying at the BWV (special treat for DD's 21st birthday trip). We had been at AK all day- a Sunday, hot and tired, and stopped at the Hess station for a cold drink before getting ready to go out to dinner (Jiko- and it was fabulous!). I was SO amazed by drink machines- don't see anything like that in our neck of the woods. ANYHOW... I think it was Tuesday morning I went to use my credit card and couldn't find it anywhere. I hadn't needed it, because we were charging everything to the room. Anyhow, I remembered that I'd last used it at the Hess station on Sunday, to get drinks. WHEW!! THANKFULLY!! We drove over to the Hess station and - WAIT!! Metal gates and chains had been erected across the driveway, and all the gas pumps/tanks were being dug up. Not only was the place closed, but the entire parking/gas pump area was GONE. Along with my credit card! I called the other station but they said there was no way to find out if the Boardwalk station had found my card or not. I cancelled the card- Chase was great- and used my DH's card for the rest of our trip. It was just so funny... I'd been SO relieved to remember where my CC card was- and then the place had pretty much vanished!
