I would like to know the official answer too. My husband is Gold and I am Plat. We booked a night using his Chase FN cert for a stay in May. Our experiences have been, Asian properties are accommodating when at check in they know one of the guests has higher status, they honor the higner status benefits. However this upcoming stay is in Europe. So a more definitive answer from the Lurker is beneficial, even though it would mean we need to cancel and rebook thru Customer Support as Christina suggested.
