I'm currently booked for The Hotel and Mandalay in August and with the new Hyatt Mlife partnership I had some ideas of how to make the most out of my trip. On a side note I'm a bit of a gambler so I'm stoked about this partnership and my current reservation is comped so I assume it won't count for anything with Hyatt. Here we go... In July I'm planning on applying for the Chase Hyatt card, before I do that I was going to enter Hyatt's Diamond Challenge which grants you 60 days as a Diamond member, and you get it for the year if you stay 12 nights in that time period. My understanding is that having Diamond status at the time of my Chase application will get my two free nights in a suite. In addition, with the new MLife partnership I will be able to match diamond to MLife diamond as well (being a gambler and visiting vegas 2-3 times per year this is huge). I'm anticipating that even if my 60 days expires on my challenge my MLife will last a year (may or may not be the case, but we'll see). My next thought was that for under $800 I can "stay" 12 nights at Exacalibur (MLife) and qualify for the challenge and maintain hyatt diamond. The big question is can I "checkin" for my stay at Excalibur and simply roll out? I don't have the ability to actually stay 12 nights during that 60 days. Also if you qualify for Hyatt Diamond is it only for remainder of year, rolling twelve months, or good through 2014?
