kenman, we stayed at the Polynesian for nine nights at the end of March into April. At that time they were renovating Samoa, laying a sidewalk from the sidewalk that runs the length of Raratonga down to the road (in anticipation of the busstop I believe), and working on pipes in the ground on the pool side of Rararonga by the large generator or air conditioner or whatever it is (near the GCH but on the pool side).
I asked a workman what they were doing there and he told me they were beginning work to replace all the water pipes that carry the chilled water to the longhouses for the air conditioning. He said they redid it about five years ago but that there were problems and were doing it over again. He said it would eventually be affecting each longhouse.
They should be finished with the renovation at Samoa by now as I believe they are about to start on Hawaii.
A fairly large part of the eastern portion of the main parking lot was fenced in and filled with construction trailers.
Despite all of this other than choosing one path rather than another a couple of days we were unaffected. It was as peaceful and beautiful as ever!
