Okay would Hilton be a better option? They have both offered to honor my Platinum status so it really doesn't matter to me either way.
To the responses above: Yes, I should've checked. However, if you are Marriott do you think it's wise to treat someone that has spent well over $40K each of the last three years at your Hotels like this? Talk about "cutting your nose to spite your face"
In addition, I stay mostly in big cities. Shouldn't be an issue even if Hyatt has a limited base.
