Las Vegas tourism is surging as travel rebounds, and visitors are flocking back to enjoy the city's fastest-growing attraction: dayclubs. USA TODAY reporters @dawnwgilbertson and @bailey_schulz visited 10 pool parties over a busy long weekend when the Grammys were in town and the final two games of the NCAA's March Madness college men's basketball tournament filled sportsbooks. They experienced a world of over-the-top celebrations, from parties with big name performers and champagne showers to $50+ drinks and daybeds costing thousands. The pool parties had some unexpected features too, ones that could trip up a first-time partier: strict dress codes, long lists of forbidden items, a lack of shade and seating. Some parties sold advance tickets but gave out free guest passes in Vegas, while others had hour-long waits to get in. To help dayclub visitors navigate the massive scene in Vegas, our reporters put together a guide to Sin City's best pool parties, from how to get on guest lists to what to wear. Read them at the link in our bio. #LasVegas
