This tour is a fantastic way to see Alcatraz and the bay area! I recommend arriving at Pier 33 30 minutes early, as the queue racks up quite quickly. The Alcatraz experience was excellent - I thoroughly recommend exploring all areas of the island, as there are some great views of the city and Sausalito. There are also some great city views on the left side of the ferry on the way over, so be sure to get a seat on the left. I chose to use my bike voucher a day after Alcatraz, as I wanted some more time to explore the city. I rode across the bay into Sausalito, which was incredible as it was sheltered from the wind and fog. There is a ferry that takes you back to the fisherman's wharf, however, I chose to ride back across the bridge in the hopes of getting some clearer photos of the GG Bridge. I rode a total distance of about 30km return and was stoked with the experience. Definitely worthwhile!
