5. Once Upon a Treetop – Plainview

This large indoor play space focuses on creating settings for imaginative play. It is probably best for younger children, but older kids, especially part of a mixed-age group, can have fun as well.

Kids can run from room to room or ride little cars and bikes. There is a climbing treehouse with a slide. Parents must supervise children, but the staff is available to encourage imaginative play. A few additional safety and sanitary measures have allowed for in-person play to continue; however, visitors must sign a participation agreement in advance. Open play hours are limited at this time, but the space can be rented for private 60-minute sessions, too. Temperature checks are required for entry, plus all visitors must sign a participation agreement waiver.

An abbreviated open play schedule is announced on a week-to-week basis. Visit the website for current hours and to reserve your spot.
