Weekend bookings set fee

Just reading where member's would like to leave at 4pm on a sunday, instead of 12 noon, does anybody think it would be worth the club say,? having 50% of pitches available for friday to sunday bookings where people could leave at anytime they like after 12noon for a set fee  of £40-50 I am not suggesting that this should happen but im just throwing my hat in the ring to see what other member's think as this seems to be a bone of contention, for some member's who wish to leave after 12 noon
