A helicopter left Venice on Wednesday midday local time, landing on Bezos’ yacht’s support ship, named the Abeona, next to Bezos’ yacht, Koru, which was parked just off the coast of Croatia. The chopper then returned to Venice with the couple aboard. The helicopter landed in the Venice Lido, where the city’s annual Venice Film Festival is held.

Yesterday on Tuesday, June 24, several celebrity guests began arriving in Venice. Among those spotted in the Floating City were Ivanka Trump and Jared Kushner. Diane von Fürstenberg was also seen arriving at Venice’s Marco Polo airport on the same day.

A source revealed to PEOPLE that the star-studded festivities, which will be spread out over multiple days, will kick off with a casual welcome night at a closed cloister adjacent to Madonna dell’Orto church on Thursday, June 26.

On Friday, June 27, the couple is expected to marry in a black tie wedding ceremony. This is expected to take place at the Island of San Giorgio Maggiore off of Venice, transformed by the Giorgio Cini Foundation into an event space.

An exclusive source told PEOPLE that Matteo Bocelli, son of Andrea Bocelli, will perform at the ceremony.

After the nuptials, guests are expected to enjoy a relaxed Saturday night evening dinner on June 28. Originally, this was set to take place at Scuola vecchia della Misericordia but was later relocated to the Arsenal of Venice — a historic site of former shipyards and armories, according to a source.

Earlier this week on Sunday, June 22, the soon-to-be groom, 61, and bride, 55, were spotted on Bezos’ $500 million superyacht off the coast of Europe enjoying a foam party with their friends.

Wearing their swimsuits, Bezos and Sánchez played around in foam that bubbled up on the deck in clouds of thick, frothy bubbles. Partygoers also bounced around giant blue, pink and yellow beach balls, and dove off the yacht to swim in the ocean.

Although many wedding details have remained under wraps, the couple’s closest loved ones have predicted that their glam celebration will be anything but a regular wedding. “I think it’s gonna be like a Princess Di thing,” Sánchez’s older brother, Paul, told TMZ in March. “It’s gonna be an amazing event. It’s gonna be star-studded and fun.”
