It is not the cost of the outfit you have - any individual can cut their cloth to suit their needs in that department.
What surprised me was the amount of restrictions placed upon us on a camp site (which we did not use in the end) plus the charge per adult, per child, per dog, per awning, per gazebo, per visitor, per car, per visitors car, and of course per caravan, per day!
It added up to more than the cost of a luxurious cottage just outside Looe in Cornwall that had a four poster bed in one bedroom, three bedrooms altogether, lounge, dining area etc etc. The propritor was great and noting was too much trouble.
I fail to see how being charged to do anything and everything whilst using your own accomadation having towed it their in the first place can make sense?
