5 groups of five. It will go faster and people can swap tables. (or wives) Maybe you can ask some people to bring card tables in case you don’t have enough.

It will just depend on how many tables you have.
We’ve had 17 players and we just put 9 people on one table and 8 on the other.
If you’re in the Dallas/Fort Worth area and ever need any more players just let me know. I am looking for other places to play. We are the ones always hosting the games.
