Don't forget warm jackets or windbreakers! It is chilly at sea even when it's 70 degrees at the shore! (The crew can supply fleece blankets.) From the deck of the ship, Privateer, we had great sightings of dolphins and grey whales on the Sunday afternoon we were out. Our naturalist/guides were eager to share information about sea animals and seemed to enjoy walking among and talking with passengers. I used Groupon to get discount vouchers, so taking our group of 7 family members was affordable. Do check on the SDWW website to learn about their own week-day deals. We brought snacks with us, but my husband couldn't resist getting a hot dog from the snack bar. It was very reasonably priced. He loved that it was cooked in boiling water rather than being grilled or nuked. A great trip all around.
