What’s the point of the Club if sites are full?

I left the Club last year because we mainly take our motorhome to Europe but I was happy to rejoin as we thought a week away in the UK might be good whilst we await new travel rules. So, having decided on a nice area in the South East and found a Club site we fancied  - it is totally booked out in June. Fortunately there are plenty of commercial sites with lots of availability in the same area and in many ways I would prefer them to a Club site.

I suppose you could say that the Club is successful by having their sites sold out, but - a “touring Club”?! Seems to me that it is a highly specialised Club catering for a few people who want a very specific experience far removed from normal camping.
