Reviews: San Diego: Harbor Cruise

Guest User2025-11-21

The experience was great: the atmosphere, the weather, the views, the comfort of the boat, the beer was very good, the crew was very friendly, and the captain gave a very good explanation. The only downside was that they canceled the first departure I had booked for 10:00 AM, and the cancellation email arrived five minutes before, just as I went to the counter to ask for information. That's where they gave me the next ticket for the 11:10 AM departure. That's the only bad thing—the message arrives a few minutes before; they should send it in advance. Totally recommended for all tourists, 100%.
