Hi, I am flying into Sacramento for 2pm tomorrow and have rented a car to drive down to San Francisco to stay for the remainder of the trip (4 days). I will be with a friend and we are wondering if it would be worth it to detour to Napa Valley for a late lunch? If not, what else is there along the way we could do/see-- that would allow us to arrive in SF no later than 9 or 10pm? We are females in our late 20s if that makes a difference. Thanks!
