Hello Ruth Schrader-Grace,
I offer a better rate for paying in advance. Divide the full rate by classes offered for a single session drop in rate. Another way is paying in advance for the full package with no refunds. It is not guaranteed that groups will sign up and attend.

Typically, when you run semi-private classes the class is listed at a specific price, not a per person rate. It helps avoid the type of situation that I believe you’re describing. If only 1 or even 2 people show up, but 4 are signed up you can either cancel class or charge the people who signed up but didn’t show up.
