Some resorts ask you to choose a version of Mexico. One&Only does not. At One&Only Mandarina, treehouses rise from a two-hundred-year-old rainforest canopy above a swimmable Pacific beach. At One&Only Palmilla, hacienda-style villas cascade toward the turquoise Sea of Cortez, hours south by coastline and centuries apart in spirit.

Right now, both properties are extending a rare invitation to Coastline clients: exceptional added value for those who book soon — Mandarina for stays booked through November 15, Palmilla for stays booked by September 15 for travel through October 31, 2026.Palmilla’s offer terms are book by September 15, 2026 for travel through October 31, 2026. 

One&Only Mandarina: Rainforest Luxury on the Riviera Nayarit Coast

Set along an undeveloped stretch of Riviera Nayarit, One&Only Mandarina feels less like a resort and more like a discovery. Eighty acres of coastal rainforest hold just over one hundred free-standing villas and treehouses, each with its own plunge pool and a private view of jungle or ocean.

Villa Cumaru, Villa Jaguar, Villa Tortuga, and Villa Pacifico each offer their own take on Mandarina’s barefoot luxury, while Villa One and the resort’s Private Homes step things up further for larger groups. Dinner at Alma, tucked into the treetops, is a Mandarina rite of passage.

For stays booked now through November 15, 2026 (travel valid through November 15, 2026, four-night minimum), Mandarina guests in every room category receive complimentary round-trip airport transfers to Puerto Vallarta and priority upgrade consideration 48 hours prior to arrival, subject to availability. Grand Villa guests — Villa Cumaru, Villa Jaguar, Villa Tortuga, Villa Pacifico, and Villa One — also receive a $450 USD resort credit and 4 pm late check-out, while Private Homes guests receive a $750 USD resort credit and 4 pm late check-out.

One&Only Palmilla: Old World Elegance Above the Sea of Cortez

On the southern tip of the Baja Peninsula, One&Only Palmilla trades rainforest for hacienda. White stucco walls, red clay roofs, and carved wooden doors set the scene for one of the few swimmable beaches in Los Cabos, with the Sea of Cortez stretched out in every direction.

The resort’s signature Villa One and Villa Cortez remain two of the most requested addresses in Los Cabos, and it is easy to see why. Wagyu at Seared, seasonal Baja flavors at Lucille’s Kitchen, and sunset views from Agua round out a dining scene as considered as the architecture.

Clients booking by September 15, 2026 can expect a guaranteed upgrade to the next room category (excluding Plunge Pool Rooms, Suites, Casitas, and Villas), plus a complimentary round-trip SJD airport transfer with any Junior Suite booking. Suite and Villa Escape Promo bookings also come with enhanced nightly resort credit, from $100 USD for One Bedroom Suites, Two Bedroom Family Suites, and Casitas up to $200 USD for Villa Cortez, and Villa One and Villa Cortez guests enjoy a complimentary seventh night. Travel is valid through October 31, 2026, with a three-night minimum stay.
