I used the long-term parking facility at Newcastle in July 2015 for one week while travelling abroad on a family holiday. I pre-booked online. Access to the car parks was easy but it took quite some time to find a space. There were signs at the entrances to some car parking sections saying "car park full" but they were plainly not. After finding a space, we (as a family) had a 10-15 minute wait at one of the bus shelters (it was raining) and took the courtesy bus to the terminal. On our return, we arrived into the airport around 04:30 and decided to walk to the car park as there was no sign of any bus at the terminal and we did not see one operating while we were walking to the car park. The car parks are well "lettered" so it was straightforward to locate the car. Exiting the car park was also no problem.
