We were very happy with the tour, Tracy gave us useful tips and thanks to her we were able to visit everything we could and wished in a short period of time. We did the city tour by bus (day & night), the wax museum, Muir Woods and Alcatraz (in two and a half days).
Big bus tours is a great way to visit San Francisco when you don’t have much time to plan your trip, they take care of everything. However, they also give you freedom to see the places on foot thanks to the hop on and off option.
