Known to some...
Not having seen this thread, I just spent time talking with an AmEx rep who had no knowledge of the two stays, five nights credit benefit. I was told that this would be entirely the responsibility of SPG, and I would need to speak with them. After a long hold, I was actually connected to an "SPG" representative, who also had no knowledge of this benefit. I was finally told (after some research on the part of the representative) that this was awarded on the annual renewal date of the card, but ended in July. I pointed out that my card renewed in June, and I was told that I would need to talk with AmEx. I can only hope that I receive this, as I lack the patience to ever call again.
