I have just tried to change a booking we had made at a CAMC site booked for July 2023. Due to some recent commitments we wanted to push back the arrival date by 2 days, keeping the length of stay the same period of 2 weeks. Used the online app. All went well except when I got to the checkout there is an extra £120 cancellation/administration fee! All I am trying to do is move the booking 2 days later. I gave up. It will be much cheaper just to keep the original booking and not turn up for the first 2 days, albeit we lose 2 days holiday of course. How can they justify such a ridiculous charge. Contacted them using their Web form and they will try and respond within 10 working days. Bet I don't hear anything from them.
