I'm already at 8 stays this year, so I am certain I need to resort to no shenanigans to retain diamond. a colleague is in a different boat. She, well call her Jane Doe, suggests making reservations in her name, listing "John Smith" as a registered guest. Jane's name and CC guarantee the reservation, but John Smith arrives, saying Jane Doe is to arrive late, and he would like to check in with his CC. Of course, diamond benefits apply to his stay. And she gets the points and stay/night credit, and might be 1000 miles away. Trust me, I know this Jane Doe, and you don't want her in your room! Consistent with established tradition, when I've travelled booking more than one room, some hyatts have generously accorded diamond benefits to two rooms I have booked. This is no secret or scandal as I understand. But something about the sceme of my colleague (with whom I am circumspect at all times) is troubling. First, she is directing traffic to Hyatt, which I suppose is "loyal". But it allows her to perpetuate diamond when she might otherwise lose it. This dilutes diamond for those who have earned it as I and others have. It also rips Hyatt off. Hyatt Diamond is gracious enough that I do care to rip them off through shenanigans. (Another FFN would increase my tendency to protect them!). With this said, how plausible is the scheme? I can see it working in the US, where proprties will typically permit a registered guest on a reservation to check in, but what about properties which require a passport (e.g. Bangkok) and eventually would anticipate seeing Jane Doe? I dunno how this gets policed, but it presents an interesting academic question to me.
