Late booking discounts

Wouldn't it be great if the CC was able to discounts on late bookings say within 24 or 48 hours of travel.  Maybey offer pitches at £10 or £15 a night flat rate,This would save on empty pitches and increase revenue for the club. Most Holidays and hotels offer this to fill rooms and flights so why not the caravan club. This could also encourage member to try out diffrent sites they may not have used before.
