The scaffolding has been up in differing spots before the pool construction was started.
When we were at WL in August , we got a personal tour of the entire resort from a really nice , long time WL cast member, but his name escapes me.
We didn't ask for a personal tour , but we are DVC members and were staying in one of the new studios over at the villas side and asked to see one of the 2 bedroom rooms if any were open .........for some reason, that turned into a 1+ hour tour of the Lodge and villas

.
Anyway ............when we walked past some scaffolding that was up around on the right side of the lodge rooms going out the walkway from the lodge to the villas area I asked the CM what it was for .
He told me that they were checking and sealing up all the upper areas of the roof line, eve's and "attic" areas to prevent any critters from entering those spaces, and taking up residence.
Not sure if its true, but thats what we were told about the scaffolding.
Disappointed that the pool is not open yet .............we arrive on the 10th of December, and really hoping they are done with the pool construction by then !!!
