The "Plant"... any idea who it is? I think we can rule out Janet, because she is the focus of the show, Joe because he was Janet's target and the gun had real bullets and Charlie because of the revelation or simulation that he killed his wife. I doubt they would portray a Muslim Marine as the plant even if some have noticed major flaws in his uniform. It leaves Tori (too dumb), Bill (too obvious) and Moira (a real possibility). This is a little like finding the mole and wasn't Bill the mole once so maybe obvious isn't bad.

However, I think they are all trapped and the hotel manager is playing the role of Ben for the "Sponsors".

Any ideas on why they are there? Withy Janet's backstory, it could be that they all have someone that wants them out of the way but why the games? I think this is someone's idea of a reality show. They are being filmed for the enjoyment of some rich spectators. They may also be bets placed on what they will do next.
