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 12 weeks (or
12 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
