Thanks so much for your response, it is the only one I have had on this board.
I have just about decided to leave things the way they are.
This whole idea was really more to avoid offending someone in the "in between" cabin as smoking seems to be more offensive to everyone than ANYTHING else. I just wanted to give them an opportunity to switch if desired.
According to Carnival, the two cabins in question are identical and there are no cabins across the hall, elevators and atrium are there.
And who knows, the folks in that cabin might end up being the "fun, join the crowd" type and not mind our constant back and forth.
And of course, I would never even ask anyone who has unpacked and settled in.
Being 54 and having traveled with a pretty much helpless (when it comes to our wardrobe and stuff) husband for 34 years, one of the big pluses for me on this cruise is ONLY having to unpack ONCE. I would NEVER ask anyone else to do differently.
As is the goal of all cruisers, or should be, I want everyone in our party and all others on board to have the best trip possible.
We are not a wild and unruly bunch but do tend to sit up late and talk, especially my sis and I. And we are early risers, drinking coffee and talking again. My brother joins us at times.
Putting his cabin as a "buffer" of sorts just seemed like a good possibility if those other folks were early to bed type or late sleepers or also in the event of smoke tranferring into their cabin or balcony.
I will contact TA and see if she thinks it's even worth messing with. I guess I should have asked her first but it was the weekend and I just thought someone on boards might have come across this before.
Thanks again for the feedback.
