AVOID AT ALL COSTS! I tried to make a slight amendment of an extra half hour to my booking an extra £19.95 was demanded. The reason given was that it ran into the following day. I was happy to pay an extra daily rate at which I booked but thought £19.95 was extortionate. That and given the appalling reviews I then came across online rather worried me and I therefore felt obliged to cancel a few days ahead of departure. However it took me over three weeks, numerous emails and phone calls and courtesy of Paypal, to eventually receive a refund. There are other reputable car parking firms out there - it's worth paying a bit extra for peace of mind. Don't go there - it's not worth the worry and hassle, not to mention the rude and aggressive manner in which phone calls are dealt with.
