I am unsure which clues are intended to be "exact" in the hotel puzzles.
A) There are N characters on this floor.
Is this exact, or does it mean there are at least X characters on this floor?
B) Character X is on the same floor as character Y.
Does this mean these are the only characters on the floor, or could there be other characters on that floor?
C) Character X is with N other characters.
Does this mean character X is with EXACTLY N other characters? Or AT LEAST N other characters?
