@GADisneyDad14 covered the basics for the Hawaii building. The Hawaii building was part of the original Polly longhouses, and suffered from the same building style from the late 60s.
At least the original Poly longhouses did not follow the original plan and not have any balconies on the 3rd floor as they built for the CR North Garden (replace by BLT) or the CR South Garden wing. At the CR there were no balconies on the 2nd or 3rd floor rooms in the Garden wing.
The (3) later longhouses that are now DVC were built in 1978 Ohau (now Tokelau), and in 1985 Moorea, Pago Pago, and Tokelau longhouses were converted to DVC in 2013-2015.
