Hi OP. I have commented on your previous posts on the resort boards about this so I will say the same here. For September, you have about the best shot you are going to get. I recommended to you that you book now at SSR and will recommend that again, unless you don't want to go if you would have to stay there. Being that you said you normally stay value I would think SSR would be ok. This ensures you a room.
At the day the 7 month window opens, have him call first thing to see about switching resorts. Have your first, second, and third ready for him. A standard view at BLT, probably not going to happen, a MK view is a maybe, and a lake view is a probably. For AKV, most likely you will have no trouble, especially if you are open to either Kidani or Jambo. You can also wait list if they're not available as well. Good luck!
