Guess who might be going to California closer to winter/spring?

One of my moms friends has a surgery thing happening and we're possibly going down to see her, for a week to a month and a half depending on what she needs, but we get to explore down there when we go, so if anyone has suggestions on where to visit if we go, let me know!

(Ps it would be southern California that we're going to, not sure what to do there)
