From experience, the average tip is $10 per person. Some people donate less, others are happy to give more. Remember, it’s all up to you: if you have had a good time, tip the guide. If you didn’t like the tour – well, don’t.

No. The Free SF Tour happens rain or shine. Plus, it’s San Francisco – one minute it’s raining, the next – glorious sun appears. Bring layers and nevermind the weather.

It's a bit tight with parking spaces around Union Square, but you can still get lucky and park in the street. Alternatively, there are many convenient car parks in the Union Square vicinity. There’s an underground garage just under Union Square – you can’t get closer than that 🙂 Most charge around $6 per hour but you can find places for as low as $3-3.50. Check out this list of garages http://www.visitunionsquaresf.com/maps-parking-transportation (just click on "park" under the map).

Yes! The route is wheelchair- and stroller-friendly, and largely step-free. Despite the city’s famously hilly terrain, our tour is makes the most of flat streets in Downtown. There might be a ramp here and there, but nothing to worry about.

Paypal and Venmo app are okay. Credit cards – nope, sorry.
