You didn't say what ship you are cruising on. The bridge isn't so wide that it should affect your view. Maybe you can wave to the captain during docking maneuvers.
As to the cabin across the hall. While the cabin can hold up to 4 people it might be occupied by only one or two passengers. Only time will tell if they are loud. Two can be louder than four sometimes.
Enjoy your cruise, it sounds like you have a good attitude. And after 60 years it is a cruise well earned.
