Great great excursion. Worth the whole cruise! Small, intimate, specialized, not too scientific for me, a lot of fun learning, good for all ages, well structured, and a nice boat captain. Could even be 1 hr longer with snacks. Great great thing, can’t say enough good things & Liz is a great tour guide. Saw whales do the bubble net feeding 2 times and stopped on Aaron Island, counted seals, tested water saline, plankton viewing in microscope!
