Everything was good, but the instructions for getting the tickets was a bit confusing. The tour operator was very helpful after a series of email exchanges.
This tour operator acts as a 2nd party, and the activities are completely separate. They may have charged more, but Alcatraz was sold out, so it was worth it. I think we could have done a bay cruise at the docks without paying the 2nd party premium.
Both activities were excellent and it was a great day way to spend a day in SF. There was some time between them, so we were able to have lunch at the pier.
