The trip comes just two weeks after Jen's last chemo treatment, so Bill decides to keep an eye on Jen so she doesn't overdo it.

But the family does manage to see the city sites -- including iconic SF locations like Ghiradelli Square and Chinatown -- and even takes a wild ride on a teacup on a carousel at the Wharf!
