Currently, I'm a Starwood Platinum, Hyatt Diamond, InterContinental 6CC Executive, and Marriott Platinum.
The best program of the above is InterContinental 6CC. It's isn't like most programs since it is a benefit program, more than a rewards program. You pay an entry fee to get into the basic level ($100 I believe), but if you stay so many nights you can move up to Executive or Ambassador status. I'm an Executive level member. The customer service is great. Any conflict is resolved on the spot with a General Manager or Manager on Duty. Guaranteed Early Check-In at 8:00 is a huge benefit for me, since I can get into my room right away after a long overseas flight to Europe from US. Plus, you can get upgraded to a Suite or Executive Level room if available. On the miles front, you get 1,000 in leiu of a rewards program. Overall, you are well recognized.
Of course the downside to IC is the lack of locations. But if you frequently travel to large international cities, they'll be there.
Hyatt Diamond is similar to InterContinental in that there are relatively few locations, but if they are where you need them, they're great.
Starwood has lots of locations, and great service. I often get upgraded to an Executive Level room, with an occasional suite upgrade.
I'm a Marriott Platinum member, but I'm not sure if this will last. I'm doing fewer hotel stays this year (more quick trips), and the 70 night qualification level is too high for the benefits. I've always been upgraded to an executive level floor. But if there is one program to drop, this is it. I'm considering trying to get status with Hilton after I get my status with Starwood, IC, and Hyatt, but I've only stayed in a Marriott a couple times this year.
I think the Marriott program is great, even more so now with the increased number of brands (Courtyard, Fairfield, etc.), but as my travel patterns change, my airlines and hotels must so too.
So I think at the end of this year I'll try to get Gold or (unlikely) Diamond in the Hilton program.
Just my opinions,
Tom
