I have some Termtime only children. Currently they pay full in TT and half in the "Holidays" which they don't really need
However more and more are using occasional days in the Hols
I need to sort out a system which allows them the luxury of only paying for TT with only a small penalty for keeping the space available accross the holiday (if that makes sense) - BUT allows me to sell their space during the hols to another child so I am full
Any ideas? (if any of that made sense.....)
