Maybe tie someone up and take them to the lobby, hot spring, or hell, even out front of the hotel, attract some new guests with a free show.
Could have something fun in the dungeon, similar to the punishments, before you fuck them.
Could have some events similar to Maria's humiliation exhibitionism event. Dress them up, parade them around somewhere, make them beg.
Make them earn it, have them do the work, some cock worship, some pampering, massage, shit like that, IDK. lol
Not my favorite, but it fits and I am sure a lot of people would like it.
Some pet play (best for F&E, but really any of them could do it in this situation), take them on walks, in the park, on a leash. Make them pee on a bush/fire hydrant, sniff each other's butts, whatever you can think of, and then remove their tails and pound their asses or something. lol
Go to the cafe or kitchen, make them jack you off into their coffee and/or on food and then drink/eat it.
How about making them orally please Ellen while she is at her desk, then you can fuck her while she is cleaning Ellen up after she came.
Dress up as a maid (naked apron, perhaps skimpier than the one they usually use there), and serve food to you and maybe someone else in the lobby or their room, then they can please us while we eat before fucking them for dessert.
