We had a couple with a boom box on our next door balcony, playing music from "my band. Oooo I Love this song."
DH asked him to turn it down because I wasn't feeling well. ( Not true. ) He seemed surprised that we didn't like it. He did say, "Let me know when you leave, so I can crank it up."
I thought it would impact our cruise, but we never heard from them or saw them for the rest of the cruise.
Another cruise......2 AM, people next door had a loud party. TV on full blast, people drunk on their balcony. I didn't hear it at first, but DH did wake me up saying "you hear that racket?"
"Well, I do now." I said.
We called Security. and they finally quieted down, only to do that same the next night, also at 2 AM. 😒
