Not sure. Suggest you call OC Parks on setting up a bounce house. www.huntingtonbeachca.gov/residents/parks_facilities/parks/orange-county-regional-park-harriett-wieder.cfm
Is there a water fountain
Marc, not to put a damper on a party but I don't think the city allows bouncy houses strictly for liability reasons.
I have never noticed an electrical outlet. But honestly, There are some great climbing structures to play on.
