I'm flying in to San Francisco and staying a night with a friend and then heading to Napa for a conference the next day. Is uber an option for a trip that long? Love to hear some ideas please!
Uber is an option (it travels throughout the entire bay area) but it's not going to be cheap. Expect to pay between $100 - $200 for an uberX, possibly more if traffic is bad or if there is surge pricing.
If you're concerned about cost and have the time, you can also take a ferry to Vallejo and then a bus from there. The ferry is around $15 and the bus is less than $3. I think the bus you would take is called the Napa Vine #10 (but not sure - definitely double check).
It also might just be easiest to rent a car.
Hope this helps!
The best plan would be to rent a car for the day.
Try zipcar as well- you can hire out a car for a few hours.
San Francisco and Oakland both have shuttle buses that run a fixed route schedule from the airport to the City of Napa. The bus will be branded with the name Evans or California Wine Tours. To access a schedule, contact Evans Transportation, 707-255-1559, or California Wine Tours, 800-294-6386.
Take The Vallejo Baylink Ferry
From San Francisco International Airport, you can flag a taxi or take the local light rail system, BART (Bay Area Rapid Transit) to reach the Ferry Building on the Embarcadero in San Francisco. From BART, walk a few short blocks from the Embarcadero station to the Ferry Building. If you find yourself with a few minutes to kill before the next ferry, you will find several wonderful restaurants and food-related shops in and around the Ferry Building to visit.
From the ferry terminal in Vallejo you can arrange ground transportation. Public transportation is available on the VINE bus route #10 from Vallejo to downtown Napa.

I'd say you are better off renting a car if you don't have to drive through the normal commute times.
The ferry idea is a good one if you can get to the Ferry Building (it's accessible by Bart and MUNI) and have some time to make your way leisurely, you can take the Ferry to the Vallejo Ferry Terminal and take the Vine. The ferry ride will take an hour from SF to Vallejo and the bus will take about an hour also. So you might want to think about how fresh you want to be when you arrive at your conference. If you need to travel during the the rush hour commute times, you might have to go to purchase your ticket an hour ahead of when you want to leave. The Ferry is $13 and the Vine is going to be just a few bucks($3). Once you get to Napa, you could hire a car using Uber.
Another option is to ask about Napa Valley tours from the info booth at the airport and see if there's any tour companies that will pick you up.

There is a ferry to Vallejo and public bus service from there to Napa. Note that on weekend mornings the ferry is replaced by a bus (fast due to no traffic but not as fun). http://napavalleycarfree.info/getting-to-around/bus/
You could also try ZimRide. Or maybe you'll find someone driving from San Francisco or the East Bay to the conference.
I second Serena's recommendation, but also believe that it's easiest to rent a car. It's a 45-1 hour drive from SF w/o traffic. If you are going to hire a driver, you might as well just spring for a proper black car or limo (and have them take you to some wineries on the way -- for instance, Ram's Gate Winery which is one of the very first wineries once you cross into Sonoma). But the drive can be really lovely and bucolic; I would just rent a car and do it yourself. A lot of locals rent cars for the day just to make the drive. Often car rental places in the city have great last minute deals -- check it out on kayak.com
Uber might be a bit expensive for a trip that long. You would be best off renting a car. Or if you can find a ride to tag along with. It is about an hour-ish drive.
Here is one idea. Renting a car and driving yourself. Napa is only 1 hr away. Directions should be easy with a GPS.
Uber is a great option. The best would be to rent a car or get a zip car for the day. That way you are on your own schedule.
I live in the sac area and actually got married in Napa. There isn't any mass transit to Napa so id say renting a car. I can't think of another way. Unless amtrak goes through napa from SF!
