This is a great tour, highlight of our trip, we saw the biggest glacier calving we had ever seen at Columbia glacier, a ~150 ft tall cave on the glacier face completely collapsed. The scenery was absolutely beautiful along the way. And many many marine animals, we saw hundreds of seals lying on the beach, several whales, three dall's porpoises swimming in front of the boat for about 5 mins, and also a couple of bold eagles. The captain was very knowledgeable, giving great commentaries throughout the tour. The boat we had was very new, about one year old, it has wide catamaran style hulls which made the ride super smooth. When we got onboard, it was drizzling in Valdez and visibility was pretty low, we were a bit worried, but as we sailed to open water and got closer to Columbia glacier, the weather got much nicer with sunshine and blue skies, so don't get deterred by the weather at Valdez. Highly recommended.
