The shuttle buses that service the satellite parking lot are standard school buses. You would do well to use collapsible (umbrella) strollers for ease in stroller storage.
Most of the Festival site is on one level.
The Middle School Auditorium stage is accessible through the wing and backstage entrances.
Unlike Walt Disney World, there are no designated stroller parking areas. Try and find an out-of-the-way corner for storing your stroller.
There are lots of family-oriented programs at the Festival, from scheduled events to the hands-on Activity Room. You’ll find most of the activities are during the daylight hours on Saturday and Sunday.
Energetic kids can blow off some steam or relax on the lawn in front of the schools. This is open to the street, so supervision is always necessary. In addition, there is a playground to the right of the elementary school across the street from the Middle School. There is a Rest Area for sleepy people (check the Festival Map).
Your kids need to be supervised by you or your designated guardian at all times.
Note that some of the folk music sessions may contain bawdy lyrics or “interesting” themes. While this is a family-friendly festival, consider this a word to the wise.
There are baby changing facilities; see the Festival map when you arrive.
