The process was as straightforward as you can get. Just make sure when coming past the petrol station you get in the correct lane. Other than that drive to barrier, take your ticket, park up then return from holiday and insert ticket at exit barrier. The car parks are surprisingly very busy so make a note of your letter, we were car park G. Footpaths to the terminal are simple. A bus will collect you if unable to walk far or kids are playing up. Great service. On exit be aware directly below the foot for your ticket on exit there is a gap that tired travellers could mistake for the slot.
