Well, see here is the thing....
The good news is there is only so much they can do at WL, and they have already done a lot of it
The bad news is they could always come up with something new !
In 2014, we booked before construction was announced and then voila, they were doing construction. The feature pool was closed. We still stayed there, but were offered compensation by Disney.
But we booked again for 2015, excited to be again at a constructionless WL.
Yep, you guessed it. They then announced more construction. No compensation this time, but we love WL so much we still stayed there anyway.
We are now booked for December 2017. We booked knowing CCV was being built. We are hopeful everything will be done by the time we visit (it looks like it will be done in June or July, with CCV opening in July).
BUT, given our track record part of me is just waiting for them to announce something *else* !!!
