While I've infrequently played ay CET properties the past few years and I have a lowly gold card, I'll likely be playing at least some in the next year or so at the Lake Tahoe & Reno Harrahs & Harveys. That hasn't stopped any of them from STILL handing me free rooms whenever I book on their site though. I don't expect to see Platinum anytime in the future either.
It's obvious to me why they chopped up diamond into levels. As a yearly diamond card holder in the past who each year quit playing at Harrahs properties just after hitting 10,000 RC's with a rather healthy profit annually, the amount of freebies I received were WAY out of whack with what I expected....and I took advantage of nearly every offer. For 3 years, my wife & I took 10,000 mile drives around the country, and I received comp rooms no matter where I booked--and we stayed at EVERY possible Harrahs including the one in Canada, multiple times. This was in addition to all those Coach purses, $250-$500 VISA gift cards, leather jackets (one of which I was wearing when my $2 royal was dealt) and countless cash handouts for just showing up.
I never thought they'd keep that type of thing going. Now it looks like some smart yuppie-type executive caught on, so they have no choice but to stick it to the players. Of course you Alan probably aren't affected by this because you likely play enough for way over the requirements for 7-Stars, correct?
