No problem with booking online and arrival was OK but finding a space was difficult, knowing where to look as it was quite full. There is no guidance as to which lane to try in the dark with limited time before flight. On return: Long delay in getting a bus back. At least a 15-20 minute wait. On departure, entered pre paid ticket then presented with £40.00 to pay on the display. Pressed help button......no reply..... Parked up and went to gate house.....Closed. Went back to barrier and called again. eventually a reply explained situation and eventually the barrier opened. No apology, no explanation just a long delay and embarrassment holding up fellow travellers.
