No literal math, but just weighing the pros and cons. None of the things that are closed will bother us. My son will prefer the big pool anyway, because it has a slide and the splash area. Having half of the resort closed means it will be less crowded. Boat transportation is still open, which is something fun we will enjoy.
Cons would be the risk of construction views and noise, but our room faces away from it, and I predict most of the big truck and noise sort of stuff will be finished by the end of October when we go. The scaffolding is already down from the outside of South Wing, so most of the work is going on inside where we won't see it.
Those are my thoughts anyway. We rented DVC points and got a very good price.
