Well, for those interested I have chosen to go with Starwood as my second choice behind Hyatt. Based on my oblective comparisons, and some phone calls to check award availability, I was leaning towards Marriott. But they were not interested in giving me a comp to elite status, even though I have spent as much as $50K/yr on hotel rooms!
Somebody asked me about lifetime Diamond at Hyatt, which is given to those with 10 consecutive years as Diamond, and over 1 million base points.
