While the bunk beds do get used by guests, the Hospitality UI doesn't recognize them as multiple beds. E.G. If you have 3 bunk beds, but 8 guests the UI will display "8/3" instead of "8/6". Perhaps this needs to be fixed on Orion's end, no idea. I wanted to make you aware of it either way.

Oh, also I would've made a comment because I think you get notified of those better, but I own the game on GOG so am not allowed to do that unless the dev enables it.
