+1 on that, locked to my corporate amex.

I was looking at changing from a Hilton property as I have reached diamond for next year and need change of scenery and food selection. Marriott was at the top of list because its the other preferred chain for my company. But now I may reevaluate. I can get away with a nonpreferred hotel, not using the corporate amex not so much.

They seem to be the only hotel chain that requires a specific payment type for their main promo.
