I was making my GF reservations tonight for Thanksgiving week and got the new code rate. The lady then checked the AP rate code and it was a little better (it is obviously already in the system). She tried to book it, but the system wouldn't let her. She then noticed that it couldn't be booked until Sunday...told me to call back then to apply that code and get the better rate. I must say the AP rate is the best rate I've seen at GF in years.
