I am not sure about what renovations will be taking place, but I do know that Its a Small World is open. It was open the last time we went, fully refurbished and it really looked nice. I am one of those who love that ride.
IASW had a long refurb recently, but it is back up and running -more beautiful than ever. As for current refurbs, I think Liberty Belle riverboat and Living Seas are among current closed attractions.
