I can't help but recommend
https://funplayworld.com/ Kids playground near me in Los Angeles! It's a place where kids can be kids without any restrictions. We had a case where my son lost a toy and the staff helped us find it right away. It's so great when not only safety is taken care of, but also the comfort of the visitors. It's also a great place to grab a coffee and relax while the kids are having an active time. A perfect place for a weekend with the family!
