I was in a connecting Cat 7 on my last trip. It was the one big negative of the entire cruise. We could hear EVERYTHING that went on next door and at all hours of the day and night. Dad had a booming voice, kid whined like crazy, they'd watch TV til 3 am, and major tantrums on the last night of the cruise. I like to relax in my cabin but there was no such thing when the neighbors were around. I didn't even know I was booked in a connecting cabin (the first time I stayed in a Cat 7, it wasn't connecting), so I never anticipated such a problem. Now I'm extra careful to make sure I'm not in a connecting. I don't like taking that chance when I'm paying for and expecting a nice vacation!
