Amazon founder Jeff Bezos and Emmy-winning journalist, pilot and entrepreneur Lauren Sánchez are in Venice forging forward with their planned wedding celebrations despite protests from activists who claim the lagoon city is becoming a playground for the rich to the detriment of local inhabitants.

The couple flew in on Wed. by helicopter from Bezos’ yacht, Koru, which was moored nearby off the coast of Croatia. They are staying at the 7-star Aman Hotel on the Grand Canal that hosted George Clooney and Amal Alamuddin’s wedding party roughly a decade ago.

More than 90 private jets are expected to land at Venice’s Marco Polo airport, according to Italy’s Corriere della Sera newspaper. Invited guests reportedly include Leonardo DiCaprio, Mick Jagger, Kim Kardashian, who has arrived, Oprah Winfrey, Orlando Bloom and President Donald Trump’s daughter, Ivanka Trump with husband Jared Kushner, who have also been spotted. 

The three-day wedding celebration kicks off Thursday with a party in the cloisters of Madonna dell’Orto, a medieval church in central Venice that has been cordoned off to isolate the area from activists who have been mounting a “No Space for Bezos” campaign.

The activists have already scored a partial victory forcing organizers to move the lavish celebrations that were supposed to culminate in a mega-party Saturday at the sumptuous 16th century Scuola Grande della Misericordia building.

After “No Space for Bezos” activists threatened to fill the canals with inflatable crocodiles to block celebrity guest arrivals that party has now been moved to moved to Venice’ ancient Arsenale shipyards located farther from the city center, according to Italian press reports.

On Friday the Bezos-Sanchez nuptial festivities are expected to take place on the island of San Giorgio, known for the Church of San Giorgio Maggiore designed by famous architect Andrea Palladio. However it is not known whether the wedding itself will take place there. There is speculation that Bezos, 61, and Sanchez, 55, may already have tied the knot in a private ceremony in the U.S.

Venice mayor Luigi Brugnaro and regional governor Luca Zaia have spoken out in favor of the nuptials, which have been dubbed “the wedding of the century,” pointing out that the celebrations are expected to bring €40-48 million ($46-56 million) to local businesses.

Zaia has underlined that Bezos and Sanchez have donated €3 million ($3.5 million) to three local institutions: Corila, an academic consortium dedicated to studying Venice’s lagoon ecosystem, UNESCO’s local office, and the Venice International University.

“Welcome to Venice, Jeff,” Zaia said a statement, thanking the couple for their “gesture of extraordinary generosity.”
