Used Mid term car park on a pre booking. Easy to find and use. Just take ticket on entry park and get bus to terminal from one of the bust stops within the car park . Buses clean and frequent about every 10 min. Journey to terminal takes about 3-4min and drops off outside. Return just as easy catch bus back drive to barrier present pre paid ticket to machine and providing you havent overstayed and additional charge is payable exit. For just turning up payment machines are near the exit. Couldn't be simpler or more efficient. Also for just dropping off/picking up spaces available free of charge.
