Ann, I do not confess to understanding the workings of the CC.[I am a member of both clubs, support both of their site and alternate each year between them when I go abroad].
It has been previously mentioned that they had a deposit system but this didn't deter people from booking more than one site. The answer to that is to make the deposit significant, and perhaps full payment in advance at peak times.
The CC is a club and I would like to think that they take notice of memebers views but of course what I want may not be what the majority want.
I wonder how much they actually loose by having vacant pitches?
