who aren't guests who've booked a room.

so that puts a duty on the hotel to at least warn these ppl about dangerous conditions they wouldn't necessarily expect.

like being able to walk into a freezer that's so cold it can kill a person where the escape lever is broken (or is sometime-y).

if it turns out the girl walked into that freezer and there was an escape mechanism that was functioning properly then the hotel is likely less liable for the girl's death. there's still the problem of her being able to access the freezer in the first place.
