The only noise we had was early morning when the crew were moving the deck chairs to clean the sun deck. It wasn’t horrible, just annoying. It was usually around 5am. I we were on the starboard side and I would recommend staying on the port side for 2 reasons. The Haven smoking area is right above the starboard suite and we could smell the smoke when we were in port. If I remember correctly, the port side sun deck doesn’t have any lounge chairs at the very front, or it has fewer, so hopefully there is less chance of the crew dragging the loungers around to clean. We did not used the sofa in the living room as a bed so I don’t know how comfortable it is, but you could always ask for a foam topper when the bed is made up. The Murphy bed in the 2nd bedroom was very comfortable according to my adult daughter. No matter what, the balcony will be fantastic for viewing in Alaska. But there isn’t a very large overhang, so there isn’t much protection if it’s raining.
