A brief overview of how my private playgroups work:

• The classes last for approximately 45 minutes.
• The groups meet the same day, the same time for 15 weeks (or 15 classes with holidays, etc.).
• Rotating homes is fine as is, alternately, one dedicated spot.
• Groups tend to work a bit better when the age range of the kids is fairly similar - and I need at least 8 full price kids to start up.
• There is no maximum amount of kids - it's more a commentary on the space available to us, you know?
• Current (active) groups get first priority in terms of time/day preferences when determining the schedule for each new session.
