I'll add that even if you're there when the preschool is in session, you can share the space. It's a large area and you can be in whatever part the preschool isn't using. They don't close the park for the school.
Nope! PlayGarden is a public Seattle park. They do host a preschool from 9-1pm on weekdays. So best to visit after 1pm or on the weekends
