We have used the car park for many years and have always been satisfied. However on this occasion, as we approached the top two car parks, one was three quarters empty and the other was half empty, there were barriers closing the entrance and stopped us entering. This meant we had to use the lower car park, which was almost full to capacity and made it very difficult for us to find a space. On the way to the terminal we saw a workman, we asked him what was the reason was for the car parks being closed, he said that it is certain people in the car park office who make it very difficult for customers on a regular basis. Passing the office i went in and spoke to Gregg, who's explanation was he keeps them closed to make it easier for people to park later in the day and was not concerned about our problem which we find totally unacceptable. It was 3 a.m. when we were parking, we found it difficult to find a space and ended up feeling very disappointed and let down as we could not get to so many empty spaces. This is not why we pay for parking, to have hassle finding a space. Not a good start to the holiday.
