K/S Humor, extremely vague description

[flagrantialuna.livejournal.com]

I don't remember a lot about the fic mostly because it has been years since I read it. I'm pretty sure it was K/S (it might have been gen?), and they were staying in a hotel (I think a few floors apart?) and shenanigans happened and one of them ended up running around less than fully clothed. I remember it being so hilarious, I kept bothering my roommates by laughing.

... tbh I can't even remember if I'm searching the right fandom because I've been through a few of them in the past five years, but I'm crossing my fingers that this sounds familiar to someone because it's seriously driving me crazy.
