With Lauren Sanchez and husband-to-be Jeff Bezos firmly planted in Venice, and VIP guests arriving thick and fast, celebrations surrounding the couple’s highly anticipated wedding can commence.

The three-day affair is expected to take place from Thursday to Saturday, when some 200 guests will join the billionaire Amazon founder and the former journalist in celebrating their marriage after a two-year engagement. The events of the week are expected to cost some 40-48 million euros ($46.5-55.6 million), according to Reuters.

Spotted leaving the five-star Aman hotel on Wednesday by luxury water taxi, Sanchez opted for a vintage Alexander McQueen one-shoulder gown for one of her first appearances in the city.

Ivanka Trump, alongside husband Jared Kushner and their children, was photographed arriving on Wednesday, while Kim Kardashian was pictured arriving on Thursday with her sister Khloe and mother Kris Jenner; they were seen later in the day chatting with actor Orlando Bloom. Oprah Winfrey and former NFL quarterback Tom Brady were also among VIPs boarding water taxis at the airport.

With the threat of disruptive protests ever-present, the venues and plans may be kept fluid, but official events are expected to kick off Thursday night at the medieval Madonna dell’Orto cloister, according to Reuters. A traffic ordinance from Venice City Hall appears to back that up, with pedestrian foot traffic barred around the 14th-century cathedral, which houses a number of artworks from the famed Venetian painter Tintoretto, from late afternoon until midnight.
