At Jump ’n Jammin in Moreno Valley, we do open play differently. No timed sessions. No “your hour is up.” Just unlimited, stay-as-long-as-you-want play in a clean, safe, indoor playground built for big energy days. While other spots cycle families in and out, we let kids run, climb, slide, and explore our giant multi-level play structure, obstacle zones, and toddler areas for one price, all day — including re-entry if you want to grab lunch and come back.
