 The USA Sevens was a financial success during its run in Las Vegas, partly because its venue of Sam Boyd Stadium was surrounded by playing fields.This allowed the complex to host the Las Vegas Invitational, a major rugby union event involving club, school, and university teams, alongside the USA Sevens.During the USA Sevens' run in Las Vegas, the entry fee for the Invitational has included tickets to the USA Sevens, providing a large built-in attendance base.
