I have given a mark of poor. There is nothing wrong with the car park or system as such, it worked well for me. My mark is based purely on the charging system. I made a booking which was a non flexible booking. I did need to, or thought I should, alter the timings for departure following a flight time change. This was an alteration by about 2 hours. no change of date or anything major just a slightly later departure from the car park. common courtesy I thought, to at least do the right thing. This change was made somewhere between 12 and 24 hrs before departure. For this priveledge I was charged again, in full! Hmmmm! Not happy! I could understand a fee of some description but full fee? really? It is very unlikely that I will use the service again on this basis. Regards, Malcolm Hodgson. 07960459549
