Pool construction is scheduled to be completed winter 2016. Initially people thought it would be completed before then. However, they have not done much work in the area and I believe they are planning to keep the East pool (next to Tokelau) open through the busy July 4th weekend.
In January 2016, you may or may not have construction on one side of Tokelau.
When the construction is completed, I believe Tokelau will be the most popular request for standard view studios. Closest to the lobby and no parking lot view.
While many believe the pool will be the end of the construction, there is certainly no guarantee.
One benefit to the Moorea building, the laundry is located in that building. Until Tokelau opens, we won't know if they decided to put laundry in that building or not. There is at least one Poly map showing Moorea as the only
DVC building with laundry (but that could change).
We really enjoyed walking from Moorea along the beach, past the pool to the GCH. Very relaxing and great views.
If you are willing to take a chance on the construction situation, go for Tokelau. If you want to be safe, Moorea is the one with the best opportunity for a garden view without construction.
I would also recommend keeping an eye on Tikiman's Facebook page. People will post pictures within a day or two of any change happening at Poly.
