Dallas, Texas, boasts the largest arts district in the country. Who knew? If on your next visit to the Big D you stay at the Joule Hotel, all of this creative wealth will be within easy walking distance. The sleek and modern Joule shows off its own artistic richness with a recently renovated rooftop terrace, a luxurious subterranean spa, and its impressive collection of original artwork from such notables as Andy Warhol, Tony Cragg, Adam Fuss, and Richard Phillips. On second thought, postpone your walk to the arts district and enjoy the city’s culture right there in your hotel.
