I think Open tournaments would make sense on a Sunday afternoon or so.

I think Novice on a Saturday would make a lot of sense in the aspect that most people probably don't have a kid that is a novice and a kid that is in high school. Open tournaments though will probably have kids only a few years younger (middle school and such) that are closer to High school age and cause conflict. Maybe Fridays can be looked into by some clubs as I know a lot of JV tournaments are done on Fridays and over with quickly.
