Home inn, go directly to the front desk to make a reservation. Can I get a discount just by reporting someone else's membership card number? Or do I have to make an appointment by phone?

If you know the name of the membership card, you can book it directly at the front desk, or you can call (the hotel front desk) without running over. As long as you enter the card number at the front desk, you can find the membership information and the corresponding discount price will come out. Asking your member's name is just a simple check. It's best not to call the national reservation hotline 400, because they may ask about your member's birthday. If you don't know, you can't do it. I hope my answer.
