I am new to expedition cruises, but I will be watching for them in the future! We did the inside passage in Alaska. And the difference in what a big cruiser experiences and what we experienced is amazing! We saw great wildlife in addition to amazing, majestic views. We could kayak off the back of the boat. We saw zillions of sea lions sunbathing on rocks. Otters floating by with babies. Black and brown bears. Many humpbacks, including 15 of them bubble net fishing. Sometimes I would look around the boat and realize that any of the four views around the boat could be in a national parks brochure. Seriously, breathtaking.
The Admiralty Dream experienced some bumps, being an early sailing after the COVID 1 year break in cruising. The toilets didn't flush for a couple of days. The staff would be the bucket patrol, or hubby and I just filled the trash can up and poured it in the toilet when we needed to flush. They got the needed parts and a plumber and fixed it. Honestly, manually flushing toilets is not going to negatively impact my dream trip! :) We had 40 people onboard and we found the staff to be AMAZING. Friendly, accommodating, hard working. I couldn't ask for more. The rooms are small, not fancy. No music and dancing on a stage! The stage is natures work! We hiked on more than one island, kayaked, took rides in the zodiak. Toured up to the Canadian border (couldn't pass because the border was still closed). Naturalists on board (and on hikes), so lots of chances to learn about wildlife, birds, and the area. We saw so many glaciers, I lost track! I recommend. Heartily.
Small, not fancy, but functional. Cabin doors don't lock.
