I suspect the only reason why some might be hesitant about having a villa in the Tokelau Longhouse is due to Tokelau's proximity to the construction that will be occurring at the East Pool. Villas on the east side (toward the TTC) of Tokelau will probably have little noise issues from the construction. However, Tokelau villas on the west side (closest to the East Pool and the Great Ceremonial House) may experience some noise issues as Disney renovates the East Pool area.
Once the construction is completed (tentatively scheduled completion date is early 2016), Tokelau could very well end up being the preferred location for PVB guests with Standard View villas. Tokelau is a bit closer to the GCH and the main Lava Pool than the other two longhouses; the west side villas will overlook the East Pool, while the east side villas will have garden views; and there is a good chance that the villas on the north end of Tokelau (2914, 2915, 3914, and 3915) will offer lagoon views (including fireworks) at Standard View prices.
