Club Rallies on Commercial sites.

I need to ask a question from the Club about Rallies held on Commercial sites still open for the rest of the caravanning community. I holiday every year at a site in Cornwall where they have two different Caravan Clubs Rallies at the same time. On several occasions I was told not to drive to the shower block as I was  crossing a rally field. The toilet block was there to  be used by all campers and caravanners on that side of the site where they were holding their fortnights rally. They even tried to block the road entrances to prevent us going through.Sorry but the remainder of us removed the blocks and continued to use them. On the Sunday meeting at 10.30 they spread all their seats across the tarmac roadway to prevent us using the block again despite there being plenty of grass around. So we just   drove  and waited while they removed some seats to allow us to pass.

Were they in their right? Not a very friendly Club group I think !!!!
