In short; the Hotel kidnaps people from different universes and time periods, and enjoys toying with us by putting us in different situations weekly. Sometimes they're interesting and pleasant, sometimes there are monsters and terrible things, sometimes there's nothing at all.
If you stay inside of the Hotel, or are back inside by the end of the week, you revert back to your condition when you arrived here. So, you may die, but you're brought back.
I see you've noted some of the other arrivals here from our world. There have been others but they've recently disappeared, I can only assume returned to their original time lines I hope. And I hope not with their original mindsets. God....
Your room is safe, nobody and nothing can get you in there. And there are usually provisions allotted. Usually food, sometimes clothes.
Just... be back inside the Hotel before the clock in the Lobby strikes midnight Sunday, the chimes will let you know.
