Why is the front desk not aimed at the gate in the hotel design?

First, the division of labor should be clear and the route should be simple. Second, because there are many people checking in or checking out, and there are many luggage, it will hinder people from going up and down the stairs. The staircase itself is one of the fire exits, and it will also disturb people who are resting in the waiting room. Thirdly, if the people upstairs are in a hurry, there may be many people checking in at the reception desk, which will block the traffic and bring inconvenience to other guests. The front desk can face the lobby, but not the waiting hall.
