Just checked my MGM-Mirage Players Club offer page and was surprised to see TI events still listed there. They included a late September shopping spree which doesn't even end until 10/1.
I confess being confused about how the TI slot club works now. There is definitely a lack of information "out there". And calls to an Executive Host who has been at TI for years remain unanswered.
It's hard enough keeping up with all the downgrades and reduced services in town. But one thing is clear to me. The last thing I would ever do is book a stay where I don't even have a clue as to how the slot club point system operates.
