We have 2-table tourneys, but since we invariably have one or two same-day cancellations, like airlines we typically will overbook the tourney by allowing 21 or 22 registrants.
If everyone does show up, we're a bit squeezed at the tables at the beginning, but that's okay. What we would like, however, would be to be able to start the tourney allowing a higher number of players at a table (e.g. 11 or 12), but not collapse down to one table until we have just 10 players left.
Thanks, Carl.
