if they have availability i believe it will be about a 10 dollar per night difference.
we're in the wing in sept, booked azz and then got the email offer with PIN (was 10.00 a night cheaper but they didn't have availability) and then the AP rate was another 5 or so cheaper than that (and they didn't have availability either.)
but if you can get it, I think the AP rate is like 90.00 off rack rate.
hope that helps! i hope they have availability for you.
