16 hotel, room 1 12, how many elevators are suitable?

More than 2 elevators. Suppose this 16-story hotel has 12 rooms on each floor, so there are 16 floors x 12 rooms/floor, which is equal to 192 rooms. This hotel is equipped with at least 2 elevators to ensure the efficiency and safety of guests' travel. If the hotel has a large passenger flow or some floors have a large passenger flow, consider increasing the number of elevators, such as 3 or 4 elevators.
