Travel Note
Luckily, distances in the Bay Area are pretty short, so you can get around from city to city in a relatively short amount of time. Fairly well-connected public transportation systems do exist in the different cities, and BART and Caltrain can also take you between different major areas. Uber and Lyft are also ubiquitous throughout the Bay. For the most freedom and independence in getting around, you may want to rent a car, though it's not necessary.
