White Space between cabins - Aft D731

[Bedruthen]

We have a cabin booked on Regal Princess on dolphin deck at the aft of the ship, D731 . It is adjacent to a void and I wondered if anyone can tell me what it is, and if that is likely to be a source of noise. We could possibly move to D729, but that puts us nearer to the smoking area on starboard promenade, which might be worse. Advice and thoughts welcome!

I believe that is a store space for crew equipment based on my memory.

Looking at it, it goes basically up and down through almost every deck, so I'd guess it's a crew stairway or storage

I'd take a few minutes to view the Youtube video of D730. I didn't watch the whole thing, but I didn't see noise mentioned in the written bullet points.
