<p>I highly recommend against taking public transit from the airport. You have to take the airport tram to the BART station first, then take BART one station north (because they stopped running trains that stop at both the airport and the Caltrain interchange), hop on BART in the other direction, change to Caltrain (and you will inevitably miss your train by one minute and have to wait for the next one), then once you get to campus, get on the Marguerite and take it wherever you’re going. By the time you arrive, you’ll be exhausted. Supershuttle is worth the ~$30.</p>
<p>@ speckledegg- You’ll probably want to bring a sleeping bag as well. (I don’t know how big your carry-on bag is). It really depends how long you’re staying (the full 2.5 days, in that case, I’d recommend bringing another change of clothes).</p>
