Expiration date on comps

So I just checked my offers and I've got some really nice comp offers but they expire on 06/30/11. We are not going until 07/29/11. What are the chances of these great comp offers being extended past the expiration date?

I'm not sure they'll extend the offer but a new offer should be out by then. From our experience July/August usually has pretty good offers....

I've tried twice to use an upgrade offer that was expiring the month previous to my stay. Once at Flamingo, once at Monte Carlo. No deal either time. Acting stupid about the expiration date didn't help either. Neither did the sweet talk....maybe because both times it was a guy phone.
