First time I've seen this thread since I don't do Hilton anymore.
I switched to give Marriott a try back in February at The Blackstone in Chicago. Since, I have had 39 subsequent nights with Marriott Rewards, while only 12 with Hilton.
This change was solely based on HHonors lack of points and/or rate promos & lack of participation in this forum. Now add the Best Rate Guarantee program experiences FTers are reporting, the loss of Point Stretchers & award redemption increases to the mix. I otherwise enjoyed my Diamond years and the properties, but won't miss the program.
