BWTs on the Peninsula: Equinox San Mateo or Bay Club Redwood Shores for fitness + socializing?

Peninsula BWTs, would love some opinions on Equinox San Mateo vs. Bay Club Redwood Shores.

I'm mostly interested in class quality (I like yoga, dance and also looking for some strength classes), and whether either location has any real sense of community. I'm single, early 40s, and hoping to meet more people organically while doing something I like and staying fit. I don't mind families at all, but I'd prefer not to be in an environment that's almost exclusively families.

Interested in shared Bay Club membership too.
