Hi, We're traveling next week to San Francisco, where we will start our road trip. We're coming from Europe, on our first great US vacation. As we planned for 2 days San Francisco visit, I could convince my wife to spend half a day to go and visit the Factory in Fremont. There was no need to convince both kids, they are thrilled. All is set with Tesla, they will welcome us on Friday 8th at 10AM. Our road trip starts on Saturday, so the rental car will only be available then. I look for options to reach the factory. We are staying in a hotel in Union Square. Advancing the car renta is one, but expensive, plus additional parking cost. And I'm not too sure about traffic. Taxi is a second choice, but an expensive one. I'm not familiar with Uber, as this is not allowed in our country. What would you recommend? Thanks!
