I'm considering trying to do the status challenge. I'm not too sure how many stays I would have during the year but would love to have it for my trip to Asia next summer (Tokyo, Kyoto, HK). The current challenge ends in April and thus wouldn't work for my stay. I'm considering giving it a go now and mattress running if needed. A few questions though to help my decision. My girlfriend also has points that she would use to redeem for some nights on our trip. Would it matter who has the diamond status as far as who makes the reservations? Thanks in advance!
