This is a real location in Hawaii. It was the site of the Elvis Presley movie Blue Hawaii. The resort was destroyed twenty years ago by Hurricane Iniki and was never rebuilt.
Kenny McCormick was washed onto the river bank after going over the Waimea waterfalls. He stumbles into the Coco Palms and is led by the "King", which is the ghost of Elvis Presley, to a lost surplus of vodka and pineapple juice. These supplies are brought back to the natives by Kenny, so they can defeat the haole U.S. Coast Guard. The natives then turn out to have peace with the U.S. Coastguard and they all share the drinks.
