How about split dates at the same venue?
Bring half the teams come in Sunday, Monday and Tuesday. Have the winners stay. Bring in the other half Wednesday, Thursday and Friday.
Playoffs on Saturday. One Woodie Flowers and Chairman's winners. One winning alliance.
- Only one setup needed.
- Given a nice venue, volunteers may stay the week. (Disney come to mind)
- No arguing who the real champ is.
Just Saying........
