I paid for the City and Sea Adventure tickets in advance for my daughter and me. When we arrived, we were able to take the bus tour of San Francisco, but not the boat tour I had paid for. We LOVED the bus tour, which gives patrons a little history of each area of San Francisco, with an excellent view from the open-top bus roof seats. We were allowed to "Hop on and Hop off" and another bus came along regularly to carry us on our way through the rest of the tour. When we went to the boat tour area, we were told that the company had recently changed owners. To get our harbor tour ride, we were told we had to make our way to the main office in a different location. Our other choice was to request a refund, although it didn't sound like it was likely we would receive it. I suggest that if you're interested in these tours, you schedule separately or wait until you arrive to get current information directly from the company.
