We ended up getting an UBER and I've been able to use SFO wifi next to Door 4 at the departure levels where I asked the driver to pick us up. The cost to Andrews Hotel was 30 USD. Same for the return trip on Monday at noon. I tipped both drivers 5 bucks each. I don't know if it's regular practice but I did and none of them refused. I have to also add the cost of 4 texts and a call from the driver who picked me up (about 5 dollars in total). Overall, pretty satisfied with the Uber rides.
