We had booked the car park for its frequency of buses. We were running late for check in and ended up sitting for 20 plus minutes waiting for a supposedly every 10 minute bus! There was already a queue of people waiting who had been there at least 5 minutes already. When we finally got to Departures, the gate had shut but thankfully they allowed our bags on to the plane. Yes, we should have gotten there earlier to the car park and shouldn't have arrived so late however if the buses had run as advertised we wouldn't have had so much stress at the beginning of our holiday. We won't be relying on a bus next time and will either be walking to the car next time or using meet and greet.
