I just called and was able to pull $80 per night off my room at WL in November. I used code BAT. The CM could only give me the rate for nights 3 through 7 of my stay, and said I would have to "check-out/check in" on day 3 and hope they gave me the same room. He put me on hold and then came back to say I could probably take care of everying on the day I first check in and all the rate changes would be done at that time. Both rates are on the same reservation number. Thanks for all the advice!!
