12 days is plenty of time to get subs OR arrange
to play a rubber or two on another day.
But, we don't the "regulars" and "alternates" thing.
We have 12 players and choose 8 per match.
Often if we warn the other captain ahead of time that we must default, we will arrange to play some or all rubbers on another day. See, we just WANT TO PLAY.......going to states and all that crap is just a PITA anyhow so we take that as/if it comes.
I got some rackets, and I got a stringer.
