I hit Diamond on MS on christmas eve last year, so this is a new gig to me, have yet to get a welcome package, can I use the Certificates that you get from the Citi Reserve card to book a Diamond only Standard award? I am asking because I am looking at booking the Hilton Auckland Harbor, and a stay the next weekend in MEL. The certs are for "Weekend Nights" and so I can use them for either, but since AKL is 60; vs 50 for MEL, I was planning on using the cert there. The issue is that when I see a room in AKL I see the following text on it : "This is a benefit for Diamond members to bypass length of stay restrictions to reserve a room using HHonors points for a standard room." Any experience with dealing with this?
