Pull the bathroom vent and see where the duct goes. If it goes over the bunk then it sounds like an easy job to cut a hole and put in a vent.
That's what I did when I added all my extra "ceiling registers". I removed a ceiling register and then stuck one of the stiffer metal tape measures in the vent hole and extended the tape to see how far the duct was cut out in the ceiling "insulation foam".
The floor registers are probably run using flexible ducting that is just laying in the enclosed underbelly and are not "cut" into the floor insulation like the ceiling registers are.
