Abu Dhabi Palace Hotel is the only eight-star hotel in the world. It is said to cost more than US$3 billion. It has a private beach of 1.4 kilometers. The decoration is luxurious to the extreme. It uses several tons of gold and countless gemstone crystals. It is said that a tree costs more than 2,000 dollars a year to support. I am also a local tyrant. I feel like a woodlouse here.
