Today's tiny victory is the word "minimal" in front of the words "water damage".
We had a radiator cap leak a bit. Thankfully we caught it early. As a bonus, the carpet tile we used in the room was rubber backed! It caught almost all of the water, protecting the subfloor from serious damage.
We've got fans on it now, and tomorrow we'll put the room back together.
The current oddity is having to climb through a bed frame to get in and out of the room.
