What parents highlight
“The reviews said it wasn’t clean and it was hot due to lack of AC— our experience was different.”
“There is also a dedicated soft-play area for toddlers, which keeps the littler kids safe from the older, fast-running groups.”
“On the day, greeted and event host (Audrey) walked us back to our party room.”
“Food: They have an on-site cafe with basic kid-friendly treats like pretzels and drinks to keep everyone fueled up.”
“Between the massive volcano slides, giant ball pits, obstacle courses, and ninja warrior sections, there was endless entertainment to keep them busy for hours.”
What parents say
Our first experience hosting a birthday party here was an ABSOLUTE BLAST! Mind you, we had come from a couple other birthday parties the months leading up to my sons (Pump it up, safari run) and my son said this was BETTER than both of those. And I agree!! Let me just say our host David was the BEST!!
Daughter likes to come here. Has different activities, but mostly geared toward younger kids. Used to be busier, or we just came at a good time. Facility is pretty clean , expect 1-2 hrs here.
Absolute sanity saver! The kids completely love this place.We took our kids to Lost Worlds Funtropolous, and they had an absolute blast running out all their energy! This facility spans over 20,000 square feet and features what feels like the largest multi-level climbing structure in Northern California.
Booked for my son's 7th birthday. Never been and heard good things. Very easy booking, had service coordinator call a week out to finalize guest list, food, drinks, etc. On the day, greeted and event host (Audrey) walked us back to our party room.
