With the downturn of the economy, the new Marriott Rewards Category 8 soon to come into effect, and the fact that Hilton has been converting more and more LXR resorts into Waldorf Astoria points earning HHonors hotels ( See 2 new Key West WA resorts announced today), we will see if this has an effect on the participation of RC in the future. I bet it does.
Some do remember that for a short time -- during another bad economy -- some RCs did give MR points - albeit in a haphazard manner, I believe.
