Amazon billionaire and space tourism advocate Jeff Bezos may have been temporarily brought down to earth this week when protesters reportedly forced one of his wedding events to move from a 16th-century hall in the middle of Venice to a more secure location, but, as they say in showbusiness, the show must go on. The 61-year-old and his fiancee, Lauren Sánchez, 55, arrived in the Floating City on Wednesday, ahead of a three-day extravaganza some speculate could cost anywhere between $US10 million and $US76 million ($15.3 million and $116.7 million). Ninety private jets, according to the London Telegraph, are bringing in tech tycoons and Hollywood high-flyers for the occasion. But there’s one thing they’ll be travelling without. What do you get the man who has everything? That’s a conundrum the who’s who of the world’s elite won’t have to ponder, according to ABC News, which claimed to have obtained a portion of the Bezos-Sánchez wedding invitation sent to guests in May. Per the purported invite, the bride and groom’s “one early request” for their nearest and dearest was “no gifts”. “Donations on your behalf are being made to the UNESCO Venice Office to safeguard this city’s irreplaceable cultural heritage, to CORILA to restore the vital lagoon habitats that protect Venice’s future, and to Venice International University to support research and education for sustainable solutions,” the invitation reads, noting the contributions to the ancient Italian city are being made “with gratitude to you for making the journey” to celebrate the happy couple.
