I am very happy with CO platinum but my concern is finding a hotel partner.

I am HIlton gold, Marriott Gold, Hyatt Platinum and Starwood Platinum.

I have come to despise Starwood, so they are out. I really like Hyatt but they have few locations where I travel so that seems kind of foolish.
I like Marriotts and Courtyards but never get upgraded as a gold. Will be interesting to see what happens when they unveil their program changes with Courtyard.

Hilton is hot and cold. Some are great, some are terrible. I am leaning that way though, especially with some of their new additions. I hope they are incorporated into the HHonors program. Guess I still have a few days to decide, but just can't seem to make a choice.
By the way I wish you all happy and safe traveling in the New Year to come. Hope to run into a few more of you in the skies or on the ground.
