Towards the end of the tour we found a group of around 200 dolphins! They were everywhere around us jumping out of the water, and swimming in groups of 2 or 3. It was an amazing experience. I wish we would have seen some whales, but that is out of the tour's control. If you don't see any whales (besides dolphins) they give you a 50% off coupon if you go again. They don't put your name on the coupons or anything, so if you plan ahead and can get one of these on craigslist or ebay before hand you can save a bunch.
The tour started off well with descriptions of the local area and local wildlife such as pelicans and sea lions. There was a ton to see until we left the bay and headed out to the open ocean. The tour also ended strongly with the dolphin sighting and more info about the wildlife as we headed back to the marina. But during the middle hour, the tour guides barely said anything, and we were left staring at the open ocean for what seemed like forever. I know that they were searching for whales with binoculars, but it would have been nice if someone had manned the microphone during this time.
Shade is hard to come by- there are only about 8 seats with shade, so if it's sunny bring sunscreen and a hat. There is also a strong breeze on board the ship, so bring a sweater or jacket even on warm days- you may need it. They have motion sickness pills for sale along with drinks, snacks, etc. Once you get to the open ocean the boat definitely rocks and pitches even on calm days, so be prepared if your prone to sea-sickness.
