Here’s the galling part: while waiting for toxicology results, motel management just kept renting out the room to other guests. If management had some something wacky like hold off on renting that room until the results came back, maybe no one else would have died.

That is an unwarranted conclusion. It's not as if carbon monoxide asphyxiation via pool heater is a common cause of death. I've never heard of anything like this before. Another possibility is that they either died of natural causes simultaneously or committed suicide via some difficult to detect means.

I’ve heard of pool heaters and driveway heaters killing people with CO. When two healthy people die in the same room at the same time, without evidence of violence or suicide, look for an environmental cause.

Right, because it is far more likely that a couple taking a long vacation committed suicide by undetectable means rather than SOMETHING MIGHT BE WRONG WITH THE ROOM.
