I'm not sure a randomizer for the inn is useful in any manner, because it's random already, and the rooms are too limited to actually 'randomize' too much or you'll end up with unable to do anything at all you'd want.
Playing like a good self-sacrificing mc, with only the squabbling, guests, and jealousy, MC has spent the night in the stables multiple times, not from lack of money, but lack of rooms people are willing to stay in, throw in the room quality demand from the previous demo, and taking a girl via duel, there's just too many people! ....and then you can just back out of the inn room selection to the city map, and go back in to have the already occupied room to change. I'd imagine a randomizer would only cause unusable setups at this point.
I'm sure there will also be other hurdles to come across we're not being shown too. Maybe wild bull will wreck an inn room and leave you with too few rooms to stay in, or outlier villages inn's being extra small...
I would like to have the girls have a little bit more personality implemented just to play into those mechanics, like on the love screen adding if they have certain attributes like being from a high-class upbringing (demanding better quality rooms), disliking particular races or even hating specific classes ("Ugh, i don't want to sleep in the same room as a PIRATE!" or "Alchemists always smell weird"). could complicate things, and give a tell for them.
Idk.
