I did call, actually, when I decided which hotel I was interested in that had it (it shows up all over the place, the first question the agent wanted to know was which property it is for).

Anyway, as it turns out, it looks like EVERYBODY is eligible for it. Its listed as "LOCAL PROMO RATE." I specifically asked the Silver agent if I could book it and if it was available to everyone, and he said yes. I also asked if I could use my Bonus Books, and again, the answer was yes. So there you go. I went ahead and booked it.

Anyone ever used it before though? Its a great deal...includes breakfast and free parking.
