Informative Caption tells us that this is “the Atlantis The Royal Grand Reveal Weekend,” which is essentially the opening of what they’re calling “a new ultra-luxury resort” in Dubai. People really came out for this, absolutely because they were gifted the trip for social media coverage and were very likely also paid cash money to attend, as well as being promised “epicurean feasts, beachside indulgences, and special reveal experiences including business class airfare, first-class ground transportation, and first-class accommodations at Atlantis the Royal.” Beyonce even performed, for which she was allegedly paid $24 million bucks (Beyonce doesn’t do any private events that aren’t very worth her time and effort, and nor should she). This was a pricy investment by Atlantis, and it worked! They’re getting media coverage! It does look like a very fancy hotel; I look forward to watching some Real Housewives screaming at each other there soon!
