Is the membership of Astor Hotel universal in China?

If you know the card number and name of the membership card, you can go directly to the front desk to make a reservation, or the user can call directly (hotel front desk) without running over. As long as you enter the card number at the front desk, you can query the membership information and the corresponding preferential price will come out. Asking your member's name is just a simple check.

You'd better call the customer service hotline, because they may even ask about your member's birthday. Not if you don't know.
