Did You Know the Wild Story Behind Mary’s Boon in St. Maarten?

If you’ve ever walked along Simpson Bay Beach, you may have noticed a charming beachfront hotel sitting just steps from the runway at Princess Juliana International Airport. It’s called Mary’s Boon Beach Resort, and while the setting feels calm and tropical today, the story behind the name is anything but ordinary.

Many visitors don’t realize that this low-key beachfront hideaway was founded by one of the most eccentric characters to ever live in the Caribbean: Mary Pomeroy, a fearless pilot, outspoken rebel, and unforgettable island personality. Her story reads like something out of a film, and it’s one of the most fascinating “did you know?” legends tied to modern St. Maarten.

A Fearless Adventurer Who Landed in the Caribbean

Mary Pomeroy was born on the Mediterranean island of Malta. After World War II, she left Europe behind and made her way to the West Indies, eventually settling on Nevis. There, she purchased an elegant historic estate called Nisbet Plantation, an 18th-century great house tied to British naval history.

Under Mary’s ownership, the plantation evolved into a guesthouse for travelers. But Mary wasn’t known for keeping a low profile. She had strong opinions about local politics and wasn’t shy about sharing them, loudly.

The Day She Took Her Politics to the Sky

One of the stories still repeated around the region involves Mary’s small airplane, which she reportedly nicknamed “Broomstick.” As the legend goes, Mary once flew over the governor’s residence in St. Kitts and dropped leaflets criticizing the government, then escaped quickly before anyone could stop her.

That moment helped cement her reputation as a bold, fearless troublemaker. And not long after, her conflict with the authorities escalated into a turning point that would change her life, and St. Maarten’s hotel scene, forever.

How Mary’s Boon Was Born in St. Maarten

While Mary was away on one of her trips abroad, her land in Nevis was seized and placed on auction. A close friend, British barrister Geoffrey Boon, stepped in and purchased the property. The proceeds from that sale were then used to help Mary acquire a beachfront location on nearby St. Maarten.

That’s where Mary created Mary’s Boon, a playful name that combines her own name with her friend’s surname, and can also be read as “Mary’s Gift.” She found her ideal setting: a brilliant strip of white sand, turquoise water, and a location close enough to the airport to suit her love of flying.

A Plantation-Style Hotel Built for Beach Life

Mary built the hotel in a Caribbean plantation style: a row of low adjoining suites with wraparound verandas, classic gingerbread trim, and gardens framed by hibiscus shrubs, coconut palms, and sea grapes. Even now, the property feels like a throwback to a slower, more personal era of island travel.

It’s the kind of place travelers love when they want something that feels authentic: beachfront, relaxed, and full of character instead of corporate polish.

The Famous “Honor Bar” Tradition

Mary’s personality shaped the hotel in memorable ways. One of the best-known traditions at Mary’s Boon is its Honor Bar, a space where guests mix their own drinks and simply report what they had afterward.

The story behind it fits Mary perfectly: she reportedly didn’t want to play bartender, so she created a system that let guests take care of themselves. It’s quirky, memorable, and still part of what makes the property feel different from anywhere else in Simpson Bay.

The Mystery That Turned Mary Into a Legend

Mary eventually stepped away from the hotel and spent more time in St. Croix, but she continued to travel frequently between islands by plane. Then, on one of her flights back to St. Croix, Mary took off, and vanished.

Despite major search efforts involving multiple vessels, the plane and Mary were never found. The mystery became part of Caribbean lore, and it’s one reason her name still sparks curiosity among travelers who stumble across Mary’s Boon today.

Why This Story Still Matters for Travelers Today

St. Maarten isn’t just beaches and sunsets, it’s also a place full of unusual characters, real history, and stories that give the island its personality. Mary’s Boon is one of those rare places where the location is beautiful, the vibe is classic, and the backstory is genuinely unforgettable.

If you’re planning a trip and deciding where to stay in Simpson Bay, Mary’s Boon is worth considering, especially if you like smaller beachfront properties with a story behind them.
