CL or not?

We had a meet up with some friends and left the CL booking to them as it was their turn to choose. It was a superb location and with good facilities if slightly compact for 5 vans, however the site can be booked online with no club membership number requirement. I am sure that this is the case for many CL's with websites along with FB booking groups etc.  It was apparent that several pitches were probably occupied by non members, I'm not adverse to this as it is similar to some club sites although wardens are then present to ensure sanity prevails. Maybe there should be categories of CL to cater for non members just so we know when booking?
