Arrival Time

I hav e been a member of the club for over 30 years and used a large numbder of the club sites. The handbook tells us that arrival at a site should not be before 12pm or a designated time for some specific  sites. I find it really annoying when people term up at anything from 9.30 a.m or are still on site until mid-afternoon when they have paid up to midday. We have found that pitches have not been available sometimes or when wardens let people on early we have been hassled to leave our pitch prior to midday. If the club makes rules then why on earth do wardens not keep them and as a customer have no idea what to expect at reception when this is mentioned.
