That happened to us once in Fort Lauderdale and we got the same runaround from the hotel.
I went to our room for my JBL mobile bluetooth speaker, returned to a seat in the lobby near reception and paired it to my 'phone and played Tchaikovsky's 1812 Overture at full volume.
We got the manager within five minutes and were offered an alternative room before the climactic sound of cannon fire was heard.
To be fair the manager was very decent about it and apologised for his staff's refusal to consider our request to be moved.
Never let the tail wag the dog.
