I think it depends a lot on what you are trying to get. "Standard View" rooms at AKL and WL go pretty fast, because there are only a limited number of such rooms. I just got AP rate for AKL savannah view in early Dec about 10 days ago; but then the vast majority of AKL rooms are savannah view.
Don't forget that these rates are offered in an attempt to increase occupancy at a time of low occupancy. That won't work unless a substantial number of rooms are available under these rates!
