Personally, I hope they stick with naming Polynesian resort building after Polynesian islands. (Bungalows are the Bora Bora Bungalows). That's part of the fun of the entire Polynesian resort.
They have renamed longhouses in the past. (I believe it was last done in 1999, so 25 years ago). Why not rename them again?
Tower seems like it belongs in Honolulu, so why not call it Oahu tower?
