The night tour is a must do. Peter, our guide taught us so much about San Francisco's history.
The tour was nice. It hit all the major points of the city. I only wish we would have had a live narrator - we had the audio version. Worth the money and it allows for you to do other things afterwards.
Everything from the bus tour to the alcatraz ferry trip was amazing. The guys were super friendly and helpful. I do highly recommend taking this package tour.
