MGM has extended this promotion through November, although they've raised it $10 to $69. You're right, it is special, available only to their Player's Club members who have received an e-mail However I signed up for the Player's Club recently and got the e-mail soon thereafter. I just booked a stay using the promo where the next best available rate, which didn't include the $35 food credit + extras, was $179. This is clearly one of the best deals in Las Vegas right now.
