I just returned from there today. I was in Cabanas 9A room 9240. I booked last minute, so may have gotten a less-desirable room. It had not been refurbished, but I had stayed at the resort twice before years ago, and I figured it was my last chance in the old-style room, which I kind of liked, so I didn't mind.
My building was right next to where they are building the tower. I didn't hear anything, but then again it was a holiday weekend. There was a construction trailer kind of where my parking lot was. There are walls up when you first enter the property, so to me it did feel like a bit of a work-in-progress, but I was solo, just there for two nights, happy to be out of frozen Minnesota, and not in my room much.
So all I can tell you for certain is that room 9240 has not been refurbished and assume that is true of the rest of the building.
