Daytime is a relatively short segment at the beginning of the game. Players will spawn in the lobby, and be asked to grab a keycard for a room. There is a variety of room keys, so choose wisely. The receptionist will explain the hotel's sleeping situation, and the players will then be asked to go to their room.
Tip - Not getting into your room results in death. After settling down in your rooms, the emergency alarm will go off. If you don't get to the lobby via the staircase or use the elevator (which they say not to use), the monster will kill you.
