We've been above the theatre at least once but I'd have to check which ship. There was some noise from afternoon rehearsals but nothing unpleasant and we are usually out of the cabin during the evening performances.
There was no early morning noise.
Thank you very much for your report, I'm sorry that things didn't go entirely smoothly.
To be able to make recommendations we probably need a bit more information. Do you want to sail roundtrip from the UK ? What did you like about Cunard?
Is this the itinerary you are considering?
Queen Anne Norway and North Cape
Queen Anne is a brand new ship, currently on her second cruise. I'm booked on a similar itinerary next June but I guess you want an answer before then !
I read a review recently complaining that there were no announcements and that passengers were expected to read the Daily Programmes - The horror !
Have a great time
