Looking at some pics of your unit, it appears that you have an outlet next to the flip up counter. If you're handy, you could possibly tie into that outlet, run a new wire under the sink and stove to the wardrobe, then up to an outlet for each bunk. The back of the outlets would probably be IN your wardrobe, but it could work. Keep the wiring below the stove so it doesn't get hot.
I added an outlet to the street-side side table of my sofa. Tied it into the outlet at the head of the bed on the street-side.
