Big bus and Alcatraz trip definately worth it. Better to book Alcatraz early as it was sold out for a further 3 weeks when we were there. Really enjoyed it. Dave and driver made the big bus a fun experience.
All in All it was a fair tour
at the Alcatraz tour they scheduled our tour to be over after their closing time so we had no way to get back to our home stop close to our condo, we had to take a cab back, if you schedule the Alcatraz tour make sure its at an early time,
also at the Haight Asbury stop, they said because of a high traffic they could not get there so they offered to stop a 1/2 mile away and we would have to walk if we wanted to see it, we ended up taking UBER the next day
Good value package with an informative bus tour that you can hop on and off for 48 hours plus other night tour and 1 hour bike hire. The trip to Alcatraz was really interesting but our tickets were for a mid afternoon departure which did not leave us much time to explore the island. In reality you can source the information yourself and arrange independently but easy for when your on a tight schedule.
