The world’s most expensive hotel room doubles as an art gallery. Featuring work by renowned contemporary artist Damien Hirst, the Empathy Suite at the Palms Casino Resort in Las Vegas can be booked. At US$100,000 per night, the Empathy Suite has eclipsed the Royal Penthouse Suite at the President Wilson Hotel; the Geneva hotel charged US$80,000 per night for its costliest accommodation to top the rankings last year.
