I also was on the cruise departing June 27 from Seattle, and I can corroborate what the previous posters have written. The whale watching in Icy Point Strait was indeed extraordinary - some of us speculated that the humpback was really an animatronic device performing for us. My other whale watch was also outstanding, and we used Gastineau Guiding. Captain Mike found a very energetic whale for us, and we watched lunge feeding for nearly half an hour - stunning. Our guide for that outing was the delightful and whip-smart Mikaela, who provided excellent commentary.
Our bear "hunt" in Hoonah was well handled, and we did indeed spot one adult brown bear, who entertained us while feeding from berry bushes. From Ketchikan (the Ward Cove terminal), we shuttled to a walk through the Tongass Forest, escorted by a fun and informative guide named Debbie. Quite a character - she even recounted her Sasquatch encounter a few years prior. If you stop in Victoria, I can recommend the "sights and bites" walk with a fun guide named Emily. She's affiliated with Hidden Victoria, and she was full of excellent insights into her city.
I was favorably impressed by my first Oceania cruise and will certainly consider them for future adventures.
