Flight
SFO is the best place to fly into. Oakland International is a good secondary option.
Travel Note
Evans is the perfect shuttle to take from and to SFO and Oakland Airport. It's cheaper than a cab, Lyft or Uber. And if you want to rent a car, you will find better deals in Napa. Sarah's Aunt and Uncle can vouch for this.
Rental Car
Hertz as of now has the best deals. Take the Evans shuttle to Napa, and then head over to Hertz for the best deal in renting a car.
Hotel
Overnight accommodations are starting to get booked up. If you would like to secure a room at the Napa River Inn please contact Celia at: celialenson@att.net or the Bride at: sarahmlenson@gmail.com.
Travel Note
If renting a car isn't your style, Lyft and Uber are easily available in downtown Napa and Sonoma.
