We now always use Meet and Greet services to fly from Luton & Stansted, as the cost differential between Meet and Greet and Self Park seems to have eroded to a point where it would be rude not to !
Drive Fly were punctual and courteous - a very good experience.
Booking proved easy. We had to wait a few minutes on arrival and if you haven't used the service before, this can be a bit disconcerting, particularly in the dark. It would probably help if the greeters had some clear form of identification, as we approached the wrong one. The return worked very smoothly. It is important to note that the greeters can only wait for 15 minutes in the short term car park before incurring charges, so there is no point in calling them too early, particularly as it takes a few minutes to walk to the car park.
