We took the full harbor cruise, 2-1/4 hours. The boat was nice, spacious, clean and smooth. We first tried to go to the top deck but the only seats available were railing seats. Bench seating with the railing sticking in towards the interior of the boat. Not very comfortable as the railing is head height. There are limited chairs and tables on the top deck. We decided to sit inside where there were plenty of chairs and tables. One thing of note, The full harbor cruise is part of the North or South harbor tours so you return to dock in between each one to let passengers off and on. Narration is where we feel this tour fell short. There are some interesting sights along the tour but the description states a history of San Diego as one of the highlights of the narration. There was no history except for what was in view from the boat, hence islands and military craft. . Drinks are expectedly overpriced with a glass of cheap wine going for the price of the whole bottle in a store. Snacks are limited with roller hot dogs that look like they had been there all day and bags of chips and pretzels type offerings. It was a nice cruise but not one we would repeat. Get a starboard side seat for the best views as that is the side most of the narration is focused on. People started lining up about 30 minutes before sailing.
