After nearly two decades of construction and multiple ownership changes, the Fontainebleau resort and casino has finally opened its doors on the Las Vegas Strip. Standing at 67 stories, it is the largest occupied building in Nevada. The $3.7 billion project features over 3,600 rooms, 1,300 slot machines, 128 gaming tables, and more than 36 bars and restaurants. The opening was celebrated with an extravagant party attended by A-list celebrities, including Justin Timberlake, Tom Brady, Cher, Kim Kardashian, Kendall Jenner, Lenny Kravitz, and Ivanka Trump. Post Malone is scheduled to perform on New Year's Eve weekend.
