This year, Google Camp succeeded in attracting a few more controversial guests, whose presence at the event went almost entirely unnoticed.
Prince William and the Duchess of Cambridge were among the guests at Monday evening's welcome dinner before the event, held in ancient ruins of the Greek temple of Hera on the island of Sicily.
So far, no pictures of the couple have been posted, but it is not a piece that the couple would attend the event that shuns almost all the press and encourages guests to bring their families.
Prince Harry also attended the event in 2017 and possibly brought Meghan Markle on that journey. Markle was later seen the following week in London with her mother when she celebrated her birthday.
Tom Cruise is also present but manages to prevent detection according to those reports.
The royals and the Mission Impossible star belonged to a select group of billionaire businessman, world-famous pop stars, doyennes of design and Hollywood A-listers who descended for the ancient Greek city of Selinunte for Google Camp.
Private aircraft and megayachts brought Harry Styles, Katy Perry and Orlando Bloom, Stella McCartney, Barry Diller and Diane Von Furstenberg, Gayle King, Leonardo DiCaprio and Bradley Cooper to the Verdura Resort in Sicily.

And according to tradition, guests enjoyed dinner on Monday and a concert under the stars in the ruins of the temple of Hera on the island.
There were cars that brought guests to the bacchanal bash, where Google decided to spread the orbs of Jeff Koons over the ancient archaeological ruins.
DailyMail.com received photos of guests on their way to the event, including Bloom and Perry, who rode with their new friends Diller and Von Furstenberg and Styles with his friends Jeff Azoff and Ben Winston.
Diller later posted photos of his old partner at the event and of singer Rosalia who took the stage.
On Tuesday even more guests arrived, Nick Jonas and new wife Priyanka Chopra who were in charge of celebrities who went to the island for the three-day conference.
Google Camp guests are encouraged to take their families with them, just like during the Allen & Company conference in Idaho that runs a few weeks earlier, and there is no shortage of activities.
The resort has two 18-hole golf courses, a tennis academy and one of the largest spa complexes in Europe on the more than 1.5 km private coastline.
There are a number of suites and private rooms, as well as three villas where guests can stay in a helicopter after arriving by sea or plane.
These villas overlook individual swimming pools, as well as the huge infinity pool and the beautiful private beach, filled with imported white sand, a jetty and even a small carpet to take spoiled stars to the crystal blue ocean waters.
There is also a dock for all yachts that have anchored.

Luxury mega yacht the Andromeda, owned by billionaire Kiwi Graeme Hart, has been seen just off the coast, just like Barry Diller's sailing ship Eos.
David Geffen's Rising Sun passed by on Monday to drop Perry and Bloom, but then continued his way along the Italian coast.
"All hotel staff and security must sign confidentiality agreements and it is an incredibly secure complex so no one can reveal anything about what is happening behind closed doors," a source told DailyMail.com.
& # 39; It's an annual event here, so it's worth more than their job. & # 39;
There are buses to drive guests around, as well as luxury cars, and the helicopter platform has been a hotbed of activity since Sunday.

The founders of Google Billionaire hold the opulent event in a valley of olive groves close to Sciacca on the island of Sicily, and invite the richest business leaders and tech gurus in the world to discuss issues such as human rights and the Internet.

After the morning sessions, the afternoons are free for guests to relax around the complex and the spa, with trips along the coast, to local wine cellars and offered tourist hotspots.
On the last night, Google spends nearly $ 100,000 on renting the 2,500-year-old ruins of the Valley of the Temples for a concert and sit-down meal, with Sting performing there last summer.
This year that event was on the first evening.
Details about this year's event are scarce because the itinerary for guests is hidden on a password-protected webpage.
It is also insisted that no one post on social media, although Geffen did post a photo of guests on his yacht last year, including Oprah Winfrey, Diane Sawyer and Dasha Zhukova.
