I think worth is subjective. How do you feel about disruptions? How much time in the resort do you plan to spend? Would any noise etc distract you?
I would not stay there at all until the construction is over, however we spend a lot of time at the resort. I found that I am not very receptive to any kinds of inconveniences due to construction and have avoided those conditions at all cost ever since we stayed at BC while Hurricane Hannah's was down. WE felt the stress the CM's were under during lunch times when they were trying to accomodate a lot of hungry people, and just did not like it.
But how are you with inconvenience, disruptions, noise etc? I think only you can determine value during construction.
FWIW, I think the food court is up and running in some manner, and the pool is open.
