The car parks were all very busy and the signage is very poor to show the actual entrance/exits to each car park. After waiting for 10/15 minutes for the free bus to take us from the car park to the terminal, we had to phone through, the bus then arrived fairly quickly. Also on our return from holiday a number of people were waiting in the queue and after 15 minutes the bus still had not arrived so someone phoned through and was told its on the way, after waiting a further 10 minutes in the rain the bus finally turned up. We even considered walking back to the car park as it is often quicker than waiting on the bus!
