We are traveling to San Francisco next week and I want to know how to schedule a ride in advance. Can I pre -book a ride with Uber? Is this reliable?
Can I schedule a ride in advance in San Francisco
Yes, you can schedule a ride ahead in SF if you are worried about getting a ride, though as RedANT stated you should have no problem getting a ride on demand.
If you are looking for companies that focus on scheduling rides in advance you can use RideGuru's Fare Calculator and look under the "Book Ahead" tab for your trip to find companies that will allow you to easily book your ride in advance.
