Can I bring 4 into the hotel room number?

Generally, there is no 4 at the end of the room number of the hotel, and the first one is usually the floor. It doesn't matter. If he lives on the fourth floor, it must be the first one at the beginning of 4, and the middle one doesn't matter, as long as it doesn't end with 4. Just leave a 4 at the end. I hope my answer is helpful to you and can be adopted. Thank you~
