We had a very limited amount of time in the city and wanted to make sure we were able to cover as much of San Francisco as we could. The hop on hop off and the bay cruise combo is the best way to do that. Our guide did an amazing job, he was hilarious, informative, and even gave us 10 minutes to get out and take pictures once we crossed the bridge towards Sausalito. The Bay cruise portion of this tour was absolutely spectacular. From the minute you leave the pier to head towards the Golden Gate Bridge, Alcatraz, etc. you are getting all kind of information about each area you see. I was excited to be able to do this portion of the combo package, because of our limited time in the city we did not have the time to go to Alcatraz. Due to this tour I was at least able to see it from the exterior much close than I could from the pier. The buses and the boat run several times throughout the day which makes this combo very convenient and easy to use.
