Car parking experience was fine with the one exception that we had 7 cases and required 2 trolleys to transport them. The trolleys were secured and needed pound coins to release them. We did not expect this and had no change with us. Due to disability my wife is not able to pull a case, therefore it took 3 trips for me to get the cases to the check in desk. The situation was worse when we returned to aberdeen from Thailand. After a total of 18 hours travelling we experienced the same thing at the international arrivals. Unfortunately I was not able to make 3 trips as I would not be allowed back into the baggage area, we were then left stranded in the baggage area, there were a number of other foreign visitors in the same boat. This system is unacceptable, tourists do not have in their possession pound coins when they arrive at aberdeen airport. I then had the embarrassment of having to ask the other passengers if they could give me change of £10 to enable me to get out of the airport. Fortunately someone gave me £2 to get two trolleys. Whoever is deciding policy at this airport needs to take a long hard look at this policy, first impressions count and if you want visitors to believe that aberdeen is such an unsafe place to be that we need to chain up trolleys then what impression are we leaving them with. I am sorry that this is so negative as it could have been a really positive experience, but if you were in my situation with 7 cases and no means to transport them then I am sure that you would feel the same.
