Before it changed to a double-tree this placed was mostly used to bring girls from Matsuyama city (red-light district near the hotel) for some closure to the night. I am guessing that every room was smoking.

The Hilton Chatan is right at the back of American Village. Good location for base related travellers unlike the Double Tree, but not as good for tourists. I agree, I'd to see new properties on the outer islands as well.
