I am sat here, feeling a bit more relaxed about it than most of you, I think it's quite innovative to use an otherwise redundant part of the ship, add something different and keep the income coming in, which is so important to the ship's long-term survival.
I am sure all fire and security regulations will be met. The ship has a modern fire detection system, just like the one we were shown on the QM2...with a person manning it in the deck 2 control room, 24/7.
My main concern is, is she getting enough visitors?
