All the rooms have been updated. I have read some reports where people said they did not have an updated room but I have followed the schedule for the last 2 years on what rooms were done when and as far as the Polynesian is concerned all the buildings were completed in December. When I was there in December I checked out all the buildings and all were done.
You can go here for updated info.
