We've an early morning 7am flight from Nice airport. Are there any gas stations close to Nice airport which are open around 5-5.30am and you can use your credit card to fill up the gas.
I've got a flight to Nice booked which is due to arrive at 23:35. Not sure yet if I'll need to check luggage or not, possibly I'll be able to get away without any. I expect I'll be out of the airport ...
