May ask which site you are on Gary?
I’m plus 4 , been away all weekend.
Most sites we use, CLs Commercial , like CAMC deliberately set a departure and arrival time. Usually 1.00 pm. As others have said it gives the Wardens a chance to tidy up , check safety aspects ,and then as they are humans have a quick lunch at 12.00 pm midday before the onslaught.
I have avoided CAMC main sites as far as possible in recent years. I prefer to check out the sites online , review their site plan , Google earth maps etc and then select our pitch. Arrive after the allotted time knowing my chosen pitch is waiting for me.
This arriving, parking up, dashing across the whole site looking for a pitch , bun fights etc🤮
Get a life! It’s a holiday🤪🤪
