We, a group of 3 couples, took this cruise a couple weeks ago. I cannot say enough good things about this cruise line. When you compare prices of Un-Cruise cruises and the "big ship" cruises, you wonder if it could be worth the extra money. The answer is yes.
We were on the Wilderness Adventurer. It holds 60 passengers and 25 crew. It is 4 floors. The lowest level is the crew level so we never saw that. The next level has some cabins, which is where ours were, the galley, the dining room and the bar/lounge. On the back of the boat, this is the level you get into your kayak or the skiff but you access this from stairs on the 3rd level. The 3rd level is rooms and the front bow where you can stand out and watch wildlife. The 4th level is the open deck and bridge. The back half is off limits because this is where kayaks and skiff are stored. There are 2 elipiticals and 2 stationary bikes and some weights on this level also.
This cruise line is very informal. You do not need to dress up for any meals. Some nights we came in from hiking and went straight to dinner without cleaning up. There is no assigned seating. There is fruit/toast/yogurt out at 6:30am, then hot buffet breakfast at 7:30 every day. Lunch is buffet at 12 or 12:30. Cocktail hour is at 5:30 with a drink special, because the Alaska cruises do not include alcohol, and heavy appetizers. Dinner is at 6:30. During breakfast the chef tells you your dinner choices, a meat option, a seafood option, and a vegetarian option. You pick one. One night, one of our group didn't like her meal so they brought her out one of the other choices. One night I didn't like any of them, so they made me a salad to order. Cookies every day with lunch and at 3pm and a different desert every night. I am a picky eater and don't eat seafood so the food wasn't my highlight. My friends loved the food, especially the all you can eat crab night.
2 twin beds pushed together to make queen. One person has to sleep against wall. Nice size window. I would sit in the bed and read with window open, very nice. 5 shelves to put clothes on. One nightstand. Small flat screen TV. Shower/toilet combo. Sink is in room.
