If you look at a deck plan you will see that it is directly above one of the theatres. We have a state room at the opposite end on the same deck and it is directly above the other theatre - needless to say that we didn't choose this it was given as an 'upgrade' on a guarantee basis and according to the travel agent we have no choice but to accept this as the ship is apparently full. I will never again book on this basis as I have now learnt my lesson on this matter. Not sure whether it will be noisy or not - its just a good job that we are night owls and don't go to bed early.
I've just been on Sea Princess and being on Emerald Deck (E304) we were next to the theatre. We heard no noise AT ALL from the theatre. We were only slightly disturbed at about 7am in the morning by people walking/running on the promenade deck but you won't have that problem being on Dolphin Deck. Sound proofing on the ship is rather good. Hope this helps.
Thank you for your comment, it is much appreciated and it has put my mind at rest as I was getting rather worried with reference to noise - I can now look forward to my cruise - thanks again.
Thank you for this and the other comments. Very helpful.
I don't see a problem as theatre shows on cruise ships typically finish around 10.30pm.
I always find that it is always best to be the loudest, late night, party go-er on board and then I am never bothered by what lies above or beneath my cabin. It is always re-assuring when I hear people complaining about noise that I have made the correct cabin choice. I do believe that the shows in the main theatres finish at a respectable time although I have never been sober enough to see the end so I have no idea how early or late they finish. I only know that , on stumbling out into the foyer, there is invariably a waiter or waitress eagerly waiting to recharge my glass. Cheers and happy holidays.
