I recently took an Alaskan cruise with my extended family. 6 adults and 3 children (3-9 years old).
We were all on the Navigation deck, almost right next to each other.
I will try and break this down a bit. Keep in mind I did this cruise as a way to see Alaska. I considered the ship to be simply a floating hotel to get me to where I was going.
Perfect location, near elevator, but no noise issues. On a corner so only one neighbor directly next to us.
