Flight
SFO, San Francisco Internacional Airport is the easiest airport to get to and from the city. OAK, Oakland International Airport is closer to the Banquest location. You can go through Oakland but that will be 1 hour or more commute to SF and Oakland is not always the safest for tourist.
Travel Note
Airbnb will be your best bet for staying in San Francisco. Its best if you want to cook your own food. Eating out prices in SF are expensive. Many of the hotels are downtown and are more expensive. The cheaper hotels are in Oakland. The Four Points by Sheraton is the closest hotel to the Banquest location. Downtown Oakland is not always the safest for tourist.
Travel Note
The ceremony's entrance to the back yard is the black metal side gate. The ceremony is being held in a residential area please be respectful of neighbors. Please do not park in their driveways. Wheelchair and handicap access is difficult due to many stairs and levels.
Travel Note
The restaurant where the reception banquet is being held is across the Bay Bridge in Emeryville, CA. About a 35 min drive from the ceremony. The restaurant has a very large parking lot, but I suggest ride share or Uber/Lift home if you plan to drink.
