Booked a fortnights parking for Glasgow airport, had selected the Paisley site, on arrival gate didn't open, buzzed intercom and told to drop cases at reception and go and find a parking space. After about 5 mins found a place then walked back to the reception area to be told I should have been notified I couldn't park in this site and had to use the Linwood site. Told girl I had just parked up but told there wasn't room, I said again I've parked up but told to collect my car and drive to Linwood site. Stressful enough going through security checks and boarding without a simple thing like parking making it worse. Contacted holiday extra's on my return, emailed back saying they were busy and I would have to wait 8 days for a reply, 8 days later no joy with my complaint, then told them I would be mentioning this on facebook and was then offered 20% off my next booking. Won't be a next time Holiday extra's
