On a cruise in December on HAL, we had one inside and one outside room. I hated the inside room and it was a fairly large cabin. When we ran into a tropical storm, it was uncomfortable for me to hear all the creaking, etc. without being able to see outside; and this type of thing does not usually bother me.
Much preferred the outside room. But, if you are determined to go with her, many people don't mind inside rooms, so give it a try. I would pass.
