Travelers in search of a certain type of glamour in Palm Springs would be hard pressed to do better than the Ingleside Inn. For kidney-shaped pools and space-age modernism you’ll look elsewhere — this Rat Pack–era institution is Spanish Revival through and through, and while it’s been brought very much up to date, the atmosphere is still steeped in Old Hollywood romance.

Amid plenty of competition in Playa del Carmen, Palmaïa, the House of AïA, styles itself as no mere hotel, but a “wellness enclave,” and sets itself apart from the crowd with an intense devotion to nature, health, and spiritual well-being. The aim is to deliver all the luxury of a more traditional resort, but in a way that’s both environmentally responsible and spiritually edifying.

Upscale tented camps are one thing, but ULUM Moab is on another level — this is unmistakably a full-on resort experience. The lobby is a permanent brick-and-mortar structure, and each unit is separated from its neighbors by a considerable distance, with plenty of interior space for lounging, as well as comforts you’d normally expect to find only in a proper luxury hotel.

The stunning 1904 Beaux-Arts building at 29th and Madison has been a hotel, under one name or another, for well over a century. But it’s hard to imagine it ever looked fresher than it does in its 21st-century incarnation as the James New York NoMad. Interiors are stylish, thanks to the fine work of designer Thomas Juul-Hanson, but not so theatrical as to put off more traditionally minded business travelers.

A good boutique hotel strikes a balance between upending certain expectations while thoroughly fulfilling others. And a Venetian hotelier must be tempted to reject the whole ornate package of Gothic/Renaissance glamour that’s characteristic of the city. Palazzo Maria Formosa, however, chooses a route that’s more difficult, but ultimately more rewarding — it’s recognizably Venetian, but with an unusual depth of character.

The seaside village of Charlestown is one of Cornwall’s most picturesque destinations, and sees its fair share of tourism, especially in the summer months. One way to avoid any hint of a crowd is to duck into one of Antonia’s Pearls, a collection of cottages, a cabin, a studio, and a Georgian townhouse restored by owners and operators Antonia and David in a style that’s chic, unpretentious, and memorably eclectic.

The laid-back seaside town of Tavira, on Portugal’s Algarve coast, is the setting for Colégio Charm House — in the 18th century an aristocratic palace, in the 20th a Catholic boys’ school, and in the 21st, a stylish and rather luxurious 20-room boutique hotel. It’s a mile or so from some fantastic beaches, but the hotel’s swimming pools make a persuasive case for keeping it local.

As stunning as Yosemite National Park is, it’s never been served by accommodations you would describe as stylish. AutoCamp changes that all at once, with its fleet of custom-designed Airstream trailers and a mid-century modernist-inspired Clubhouse that will have you wondering if it might not be time for the Park Service to update its architectural style.

In common usage, “chouchou” is a French term of endearment — but in the Parisian hospitality world it’s the name of a charming little boutique hotel right by the Palais Garnier. It’s chic and colorful, with a surplus of personality, and its diminutive name suits it — in contrast with the self-seriousness of the grand palace hotels, this is a fun and stylish hotel, but also an affordable and accessible one.

It’s not easy to build in a city as deeply historical as Rome, and many hoteliers are forced to make compromises. Once you’re at the level of a Six Senses, however, it seems anything is possible. Six Senses Rome occupies a historical palace, in this case the 18th-century Palazzo Salviati Cesi Mellini, a former cardinal’s residence whose exteriors and architecture have been meticulously restored and preserved.

A few minutes’ drive from San Luis Obispo, Cayucos is a California beach town that remains accessible, affordable, and blissfully underdeveloped. It’s here, a block and a half from the ocean, that you’ll find the Pacific Motel, where a local couple — a contractor and interior designer in their professional lives — have turned an unremarkable motel into an unforgettable seaside boutique hotel.
