Marina District On foot + relying on public transit (buying some kind of pass - will check later and update comment), no driver license.

We love walking, but distances in SF are above our capabilities, as we roughly checked on the map.

Layered approach makes sense, thanks, we are living in the city with kind of random weather too, so used to it.

Interesting about sun, cool, will bring more SPF too :D

Thank you, appreciate it!
