Easy to book and convenient to use however I have only rated it as acceptable because a) on the outward journey the car park was pretty full and we had to drive around numerous bays before we could find a space. b) we returned from our holiday at night and it was impossible to see the letters for the car parking bays. why are the signs not lit at night? c) the driver on the shuttle bus on our return journey was clearly not happy in his work and showed no interest in letting his passengers know which parking bay we were at even though numerous passengers were asking where we were!
