Was it your toddler?
My toddler was at home so we would have a relaxing weekend. Needless to say, we were not pleased that the walls weren't thick enough to block out the sound.
Honesty, had they just offered the suite upgrade without cash, I would have taken it. I get that there's an element out of their control here, but a 4* hotel should have soundproofing.
The other Hyatt I made a noise complaint about a couple years ago (Regency Baltimore), the noise was from the hotel bar, and specifically had requested a quiet room at check in. In that case, I absolutely blamed the hotel, and they gave a free night plus breakfast.
