About Dallas

Learn more about the host city, Dallas.

Dallas, the ninth largest city in the United States and the third largest in the state of Texas, is an impressive melting pot of culture and character. Boasting high-end luxury hotels, innumerable fine dining spots, and one of the busiest airports in the world, Dallas maintains an upscale ethos reflected by an affluent population, world-class museums, and a shimmering modern skyline. Its history was marred by the infamous assassination of U.S. President John F. Kennedy, but there is more historic and contemporary heritage to be discovered in the city.
