BY PLANE:
The Stanford Park Hotel is equidistant to the San Francisco International Airport (SFO) and the Mineta San Jose International Airport (SJC).
The San Jose airport is slightly closer and won't have the fog delays that San Fran can be famous for, so if you have a choice, we'd recommend flying into San Jose.
BY CAR:
For Angelinos looking to road-trip it, the hotel in Menlo Park is about a six hour drive from Los Angeles.
AIRPORT TRANSPO:
Taxis from the airports can be expensive (especially from SFO). UBER is a much more cost efficient and pleasant experience from SFO. Unfortunately, there is no Uber at the San Jose airport, yet.
Since we will have shuttles on Saturday, and Ubers are pretty ubiquitous, we don't see a need for you to rent a car, unless you plan on extending your weekend into a longer vacation.
