I've booked a car via BA for a holiday in France. They state it will be "FullsizeManual Group H - Citroen C4 Picasso or similar" Originally we were just 2 adults + child, now we will be 4 adults and a child. I'm not sure how big the boot is and if we will be able to fit everyone plus 4 or 5 suitcases ! We only need to fit the luggage in for 1 hr drive to/from the airport. The rest of the time we will travel without luggage. Appreciate experienced owners feedback! Cost of changing the car with BA is ridiculous (an extra £1400 to upgrade to 7 seater !!!!!!). I will never book a car with BA again and strongly recommend people not to do so.
