I've been parking at Luton almost every week all week since February as I am travelling to Inverness and will do through to 19/12/14 and may be early next yerar as well. There is no alternative to Apcoa on airport parking as even their partners are bound by their rules. I am still very annoyed that they would not allow me to modify my parking (book for the remaining days ,I would have ccept ed having to pay a full day rate for the first day) when I missed booking last week, i.e. I entered the car park and not for the first time I had to take a ticket, but realised on checking that I hadn't pre-booked. The upshot would have been a bill for £180 had I not managed to get my wife to retrieve the car on the same day as I parked it, still incurring a £36 charge. This lack of flexibility is in my view, on Apcoa's part, unacceptable behaviour and I feel like I would have been robbed had I had to pay the full amount! I have also learnt to pre-book to midnight on the day of leaving (no additional fee) instead of 2 hours after landing as once I had to pay an additonal £36 full day rate for being 30 minutes over the one hour "grace" period.
