I paid the extra to save myself some time and energy but didn't find that to be the case. The drop off place was not signposted clearly (or possibly at all) and I had to go round a couple of times, which meant I had to pay £6 to get out and back in to the carpark. The desk was not manned at drop off or pick up. Pick up took ages, when I called the number the chap I spoke to was very rude and condescending. I checked my mileage before and after and 34 miles of fuel had been used in my absence. When I queried this I was told that is normal as they have to pick up and drop off other drivers. It would have been 1 star but the man who took my car on drop off was lovely and very apologetic for the delay. I will save myself some money and get the shuttle next time.
