Definitely (love route) content for the side elves, need my Nia/Ann/Sylvia fix (Syniann?). If that's not a priority for the time being (we theorized that particular route may be linked to Lin's story a while back, although I don't know how true that actually is), I'd also enjoy some further developments with Kate. Bonus points if Juliet is involved somehow, not necessarily in the lewdness aspect although it would also be a welcome surprise.
Maybe some other type of expansion for the hotel as well, as far as real estate goes. I guess there ain't much that would fit an actual hotel besides a bar... maybe a restaurant of some variety? It would provide a convenient excuse for inter-character interactions that don't involve exclusively the hotel and/or the bar. Could also go all the way and employ the elves there, you know, give them some prospects for the future if you're planning to follow that route.
Speaking of employing the elves, that drow we keep seeing ("Serni" I think? It's been a minute) would make a good bar bouncer, assuming we can and want to help her out of her current predicament. Just putting that out there.
Other than that, some more interactions between the characters would be a nice addition I think. We rarely get to see the android and Autumn (for example) interacting other than during that initial encounter. Maybe some more Ashley/Emma/Felicity moments, or have any of those run into Kali and/or Ellen. Give the whole "big family" feeling to hotel.
