Based on location of those who had issues, and those who didn't, my sense is that this is mostly isolated to a small set of cabins on the starboard side. I was in 8746 and @justpinky had issues in 8742 which was 2 doors up from us. Seems cabins in this direct area on the port side didn't have as much of an issue. And anyone in the larger cabins (starting at 8736 starboard, and 8136 port side) also had no issues because they are clear of the theatre below (you can check the deck plans and you'll see which cabins on Deck 8 overlap the theatre). As I mentioned, location itself is great -- the noise, not so much!
