The tour was great; the highlight for me was being able to see all the military ships docked for servicing along the harbor. Everything from a nuclear-powered aircraft carrier to destroyers, to freighters, being someone who doesn't live along the coast, it was fascinating to see. You also get to go under the Coronado bridge and see the island. You see some sea lions, but its pretty fast, so I wouldn't say it is a highlight of the tour. A word of advice; the deck gets somewhat hot with the sun beating down on you for two hours, so I would. Overall, definitely worthwhile!
