Double ditto. Their unreasonable request means they think the world revolves around them. I second the idea of telling them to boondock where they can be king of their own little stump. Or get ear plugs. Or close their windows on your side. You aren't playing music. You aren't running a generator. Many campers run their AC in FL to keep the humidity in their RV under control and to keep wood fire smoke out of their rig because of allergies.
If they act that way towards others it wouldn't surprise me if they awaken sometime to four flat tires. Saw it happen to a campground prima donna back in 1984.
