Oakland is the closest to the area to fly in to! Often, you can find budget airlines as well as larger airlines flying in. Usually flights are more expensive than San Francisco
SFO is usually the cheapest place to fly in to and has a lot of options. Depending on traffic, it can take anywhere from 30 minutes to about 1.5 hours to get into Oakland. Taking BART from SFO to Oakland is quite easy and helps to avoid some of the traffic of driving over the Bay Bridge

This hotel is about 12 miles from the venues (15-20 minutes) and is in one of our favorite areas to visit! Located in Jack London Square, there's a lot of fun restaurants to visit and our favorite winery, Rosenblum Cellars (Saige recommends the Hooks Bay Sauvignon Blanc but their bubbles flight is nothing to say no to either!)
If you'd like a more upscale hotel, Claremont is the way to go! Located 7 miles (10-15 minutes from the venues), it is just a short drive to get to downtown Berkeley where there's endless things to keep you busy
The Graduate hotel gives you the feeling like you're attending UC Berkeley! Located right near the downtown, you are walking distance to a lot of fun activities! About 10 miles (25 minutes) from the venues
