Vegas runs on tourists but locals make the scene. The residency-style congresses that happen on the Strip pull dancers from around the world, but the weekly socials that anchor the city's community happen in the suburbs and off-Strip venues.

The Strip hosts the congresses and the big weekend socials. Henderson and Summerlin run the suburban studios and weeknight nights. The city has an unusual mix of styles — traveling instructors move through constantly, so the curriculum shifts often and the community absorbs new techniques fast.

Vegas is welcoming to visitors by design. If you're in town for a conference and want a night of dancing, just show up. Bring a water bottle — the air is drier than you expect and you'll sweat more than usual.
