Places for toddler in CA

Hi,

My husband and i made a last minute west coast trip plan, for end of this month. We will cover LA, SFO and LV.

Wanted to dedicate one day entirely to a place our 2 yr old daughter will enjoy. Not universal (Been to one S'pore & FL) and not legoland or any zoo/aquarium.

Counting on helpful indusladies :)

It neednt only be SFO, can be LA , san diego or sanjose or another place in CA. We can alter our itinery.

Thanks!
