+1 for moving to Plaza deck forward/midforward. That is our go to on Grand Class ships. My wife and I along with 2 children did many cruises in inside cabins. From youth to adult. By the second day everyone will have a routine and things will be fine. I advise you stay in a cabin convenient to public spaces. An inside cabin is for sleeping, showering, and changing. That is all. The best views of Alaska are not from a balcony cabin. The best views of Alaska are from the many, many public areas with blankets, hot chocolate, and a server round tripping the bar and kitchen for you. Enjoy your trip.
