Whose fault was in this hotel incident?

Last vacation my wife and me stayed at a Country Inn and Suites.
Accomodation was great blah blah blah...
Around 9 pm we decided to practice reproduction.
Thing is that the headboard was not properly attached to the wall, and an annoying banging was produced towards the next room.
Nobody complained.
At about 10 pm, the need for preserving the specie came again to us, so we started our job again... more banging, moaning, etc...
Again, luckily, nobody complained.
Okay, it's 11:30 pm and we don't feel like sleeping yet, so, while watching Conan, we get mushy mushy again and the banging starts one more time...
This time our "probably tired" neighbors start to punch the wall like maniacs towards us like the hotel was on fire...
Fortunately we managed to come anyways.
Questions:

Was our fault for being on heat?
Was Country Inn's fault for not attaching properly the headboard?
Was Country Inn's fault for constructing such poor walls?
Was the neighbor's fault for being awake?

The polite and curtious thing to do would have been to leave the defective bed. The procreation should have then taken place on the table, floor, or balconey (if present).

However, the true blame lies in you cause you "worked it" instead of being a minute man. Everything would have been fine if you would have done the duty in 30 secs or less like the rest of us.

All of the above.
Really!
So did they punch a hole through the wall? or did the headboard damage the wall?

I'm not sure what you're tying to find the blame for? Was there any physical damage that occurred or just emotional?
3 times in one night? my dear sir, this is not about fault, but about admiration!
my advice, if no one is trying to get you in trouble, then forget about it
Did hotel management ask you to come again?
