One of the first tastes of the high life for Anna Delvey (Julia Garner) in Inventing Anna happens aboard a luxury yacht in Ibiza — a gorgeous Mediterranean island known for its parties. But the trip isn’t exactly planned.

It’s already evening in New York City when Anna and her boyfriend Chase Sikorski (Saamer Usmani) make a snap decision to go to Ibiza, in hopes of meeting with billionaire venture capitalist Henrick “Hen” Knight (Josh Malina) on his yacht. The catch? They have to arrive in Ibiza in time for an 8 PM dinner onboard.

But would that even be possible? And how much would it cost? Turns out it’s easier — and cheaper — than it sounds.

We began our online flight search at about 5:15 PM on a February weekday, figuring that was how Anna and Chase booked their Ibiza trip, which kicked off during Labor Day weekend in 2014. Almost immediately, we found a one-way Delta flight from New York’s JFK airport at 7:30 PM that would arrive in Ibiza at 2 PM the next day — all for a cool $340. That might be doable, time-wise, as long as there was no traffic and we didn’t bother packing, though a checked bag was technically free. Our four-hour layover in Madrid would make the whole thing longer, but there are no direct flights from NYC to Ibiza.

When we talked to luxury travel expert Bridget Cohn, founder of Bee Hospitality, she said that the price sounded suspiciously low and that itineraries like this — one stop only, a reasonably short layover — are usually around $500.

“If there’s a good deal going on, it could be as low as [$340],” she says. “[But] booking Labor Day weekend, on one of the hottest weekends, it’s going to be closer to $700 or so for one way.”

It’s when yachts are involved that prices get really steep. Anna stole a week of “boat time,” which Hen’s girlfriend Talia (Marika Domińczyk) tells reporter Vivian Kent (Anna Chlumsky) is roughly the price of “Hen’s Tesla.” But Teslas have come a long way, baby, since 2014. So, in today’s dollars, just how expensive was the boat time Anna stole? 

“For a week, I would be comfortable saying $500,000,” says Cohn, who regularly plans luxury yacht trips for high-net-worth individuals. “For example, I’m working on a request for a client who’s doing a weeklong charter in Italy. And I have some yacht options for them that are ranging from between $400,000 up to a million for a week… You’re definitely looking at six figures.”

But Anna and Chase don’t have to pay for any of that, so what do they care? The real question is: Could a guest sneak back onto someone’s yacht, Anna-style, after everyone — including the owner — has said goodbye and left?

“There’s always security at the marinas, but I would never say never,” Cohn says. 

Fair enough! But let’s say a guest like Anna did sneak back onto the yacht. Would a guest be able to convince the captain and crew to extend the trip for another week?

“I’m sure it’s possible, but… I don’t think it would ever happen, because the whole crew would lose their jobs,” Cohn says.

Really? 

“It’s a very serious operation,” Cohn explains. “There are so many nuances and so many details, and the crews are so on point, and the communication amongst the team is just beyond crucial all the time. There’s so much respect that owners have with their teams and their crew. It’s such a prestigious operation for the crew. They generally are very proud of the boat and the whole experience. Just knowing the way the dynamic is and the relationships and how professional and tuned in the staff is to any operations — anything going on, any trips, any charter, all that... Yeah, I don't think that would realistically happen.”

The verdict? A last-minute trip to Ibiza: absolutely within reach if you have a credit card with an available limit of at least $1,000. A week of yacht time: less so.

The last-minute one-way flight itineraries we found online — including slightly pricier ones that were shorter and left later at night — had early-afternoon arrival times and mishap-avoidant layovers of at least 90 minutes. So after the 15-minute taxi ride (about $15) to the port, we’d still have plenty of time to get on the yacht for the predinner Dom Perignon sabering. Gratis, of course.
