Booked Drive Fly via APH with my Tesco points. I use parking sites quite a lot and this parking facility was just as efficient as any of the others have used. I parked in a gravel car park and the bus was ready and waiting to take me to terminal 3 Heathrow. On my return Journey I rang after collecting my bags and the minibus was at stop 22 within 10 mins. I think the cost of this facility is cheaper than the others as it seems a new operation and the cars are on a gravel storage site rather than tarmac (which is perfectly acceptable to me). So if you are happy to have your car stored on an enclosed site with a gravel surface this company is fine.
