According to the Rec Manager at the BC/YC from a previous thread on the resorts board - the pool will be closed in three phases. I think they were Oct. Then Nov-first part of Dec and then Jan-Feb. Each part of the pool was to be closed in those phases and the slide part was the last phase.
At the time the manager was asked - MS knew nothing about any pool closings at BC/YC. So now they apparently know about some of it?
Just relaying some history here - of course, anything could have changed.
