I booked a campsite based on the distance given to a venue I was attending an event at, where a site came at the top of the list being only 3.1 miles away. I've since looked on google maps and it's apparently 9 miles away, so I think pitchup must be calculating the distance based on a straight line rather the actual distance by car / on foot. This statistic was misleading and didn't clarify on the site, as a result I had to cancel and lost some of my deposit.
