Heads up, high rollers hitting Vegas for the Formula 1 race! American Express is launching a super-exclusive Centurion "1850" pop-up lounge inside the Aria Resort & Casino from November 13th to December 17th. Think of it as a super-secret, members-only club within a club. Why should you care? Well, if you're a Centurion cardholder (Amex's ultra-premium, invitation-only card), this is *the* place to be in Vegas during the F1 madness. It's a chance to escape the crowds, enjoy some serious perks, and network with other high-spending travelers. Even if you are not a Centurion card holder, it is useful to know about these pop-ups in case you might qualify in the future.
