Handling withdrawals in long Group Match Play tournaments

Hi all. I am planning one of those 24-hour Group Match Play tournaments people are always talking about. :relaxed:

One thing that concerns me is people getting fatigued and wanting to drop out of a couple rounds and come back or just getting frustrated and dropping out altogether. Should I permit temporary withdrawals? (And how would I handle this in MatchPlay - just deactivate the player and reactivate?) And what if a player drops out too early? Would I have to deduct them from TGP?

I am trying to find a way to compel people to play the whole tournament while being humane to those who will find this type of endurance event difficult. Do you have any ideas? Thanks in advance!
