I did Harv and Marv and was on a boat with 12 ppl. They met us at the port, on time, took us out and Captain Shawn was very knowledgeable about the whales. He knew where to wait and for how long. The young girl that was on board was extremely knowledgeable and had incredible amounts of information on all the sea life.
There were only 4 of us that went on this excursion but it was perfect. Our guide was knowledgeable and patient with us first timers. They were always friendly and polite.
The naturalist on board was another knowledgeable guide and was on his 2nd summer. Once we got to Glacier Point, the guides greeted us. They prepared sandwiches for us and we headed out.
Again, they knew everything. Highly recommend this tour.
