I have recently received a flier for a well known site in Dorset. Whilst calculating the cost for my wife and self to visit this site and to include electric hook up I was amazed to read that the electric is free but we were expected to pay £2-50 per night for the higher of the electrical socket. I have never come across this before in over 30 years of caravaning, is this a new twist to try and justify site charges? Your observations on this would be very much appreciated.
