Strengths & trade-offs

One&Only Mandarina

Strengths

  • Treehouse and cliff villas widely called some of the most striking architecture in Mexican hospitality
  • Total privacy per villa, with many guests reporting they saw almost no one else
  • Jetty Beach offers a rare protected, genuinely swimmable stretch for this coastline
  • Carao consistently named the standout restaurant on property
  • Wildlife program (coatis, on-site biologists, canine unit) adds a real sense of place

Trade-offs

  • Golf cart waits of 20-60 minutes are a persistent, non-seasonal complaint across years of reviews
  • Service swings from genuinely warm to scripted and inconsistent, with recurring staff turnover cited as the cause
  • Nickel-and-dime moments (bottled water charges, $700/hour jet skis, disputed currency exchanges) undercut the price point

One&Only Palmilla

Strengths

  • One of the few genuinely swimmable beaches in Los Cabos, plus private rocky coves
  • Butlers who deliver real, specific gestures rather than generic turndown service
  • Mature gardens and 1950s hacienda architecture that feel distinct from newer Cabo builds
  • Assigned pool spots that hold for the length of a stay without a dawn scramble
  • Strong kids' club and family pool setup with a splash zone and zero-entry

Trade-offs

  • Food and drink pricing is aggressive even by Cabo standards, with basic items running well above comparable resorts
  • Housekeeping and turndown can be inconsistent, including reported lapses with linens and room resets
  • Rooms in some categories read as dated next to newer competitors nearby
  • Management-level problem solving (billing disputes, service recovery) draws sharper complaints than front-line staff

Staff get named and praised constantly, but golf cart waits of 20-60 minutes, slow towel service and a recent run of turnover complaints show up just as often.

Design
19+2

Treehouse and cliff villas built into the jungle cliffside draw near-universal raves for the architecture, even from guests who left frustrated with everything else.

17

Hacienda buildings from the 1950s wrapped in decades-old gardens win people over, though several guests call the rooms dated next to newer Cabo builds.

Location
18.5+0.5

The setting an hour from Puerto Vallarta is the draw, but the resort is spread across a hillside so almost every trip out of your villa means a golf cart ride, not a walk.

18

One of the few genuinely swimmable beaches in Cabo, three private coves, and a golf course threading the canyons, though the undertow can be rough for kids.

Dining
15.5+1.5

Carao gets both the most love and some of the sharpest complaints about an off night, while extras like $15 bottled water when the free filtered option goes unmentioned wear people down.

14

Breakfast at Lucille's and the omakase at Hoshi land well, but two food-poisoning reports and a $20 horchata put the price-to-plate ratio in question.

Wellness
16

The spa draws consistent praise as one of the best guests have had, though a stretch of reports mention closures for renovation and scheduling mix-ups with treatments like the curandera sessions.

The Verdicts

One&Only Mandarina

The reason to book is the villas, and the reviews back it up. Cliffside architecture cut into the jungle above the Pacific, private plunge pools, and views guests keep calling among the best they've had anywhere, treehouse or cliff. Jetty Beach is the rare genuinely swimmable stretch on this coast, thanks to the protective jetty, and Carao gets named the standout table on property more than any other, with the fish chorizo and tacos coming up often. The setting and the villas are the reason to book, and they hold up.

What you're trading for that seclusion is a property so spread out that golf carts become the whole logistics of your stay, and that's the real cost here, not the bugs or the heat. Waits of 20 to 60 minutes show up routinely, even at low occupancy: one traveller waited over an hour on a Tuesday in July with the resort near 40% full, after a host had promised ten minutes. There's quietly upcharged bottled water (ask for the free filtered house water instead), a $700-an-hour jet ski, and one guest was handed a cash deposit back in pesos instead of the dollars they'd left, then charged a commission to convert it back. Staff turnover explains why service swings: one host tracked down two O&O hats for a guest who wanted souvenirs, while other shifts feel scripted and hover without actually helping.

The food outside Carao is good rather than great, and the wildlife program, coatis raiding minibars, a canine unit, on-site biologists, adds a real sense of place few resorts bother with. Book it for the villas and the privacy, ideally November through February for the better weather and fewer bugs; travellers wanting steadier, more predictable service tend to end up next door at the Rosewood instead. If the cart waits or the small nickel-and-dime charges would eat at you, weigh that before you book. For the setting alone, nothing else on this coast looks like it.

One&Only Palmilla

A junior suite with a plunge pool runs somewhere around $1,400 a night before you've ordered a drink, and the drink will be $30. What you get for it is a genuinely old property: hacienda buildings from 1956, gardens that took decades to grow in over a desert that gets seven inches of rain a year, and a beach you can actually swim at, which is rare in Cabo. The butler program is where this hotel earns its keep. People come back with stories: a star map left in a room after a stargazing conversation, a birthday cake arranged with zero notice, a maternity massage where the therapist knew exactly what was and wasn't safe.

The food and drink pricing is where it gets ugly, and it's worth saying plainly: a small guacamole running $35, margaritas at $30, a $20 horchata that tastes like every other horchata. That's on top of room rates that already sit at the top of the Cabo market. Housekeeping has real gaps too. One guest got a soaked, mildewed duvet re-covered with a dry blanket instead of replaced. Another spent 36 hours chasing down drinking water because there's no bottle station or shop on property. The service can be extraordinary and inconsistent in the same week, and the standard seems to depend heavily on which staff member you draw and whether you booked through a travel advisor.

Families do well here: there's a real kids club, a family pool with a splash zone and zero-entry that beats the adult pool for space, and a beach walk that's quiet even in season. Couples looking for old-school Mexican grandeur over a newer, glossier build will get exactly that. If your priority is swimmable water and a hotel that feels lived-in rather than freshly built, book it for the beach and the gardens.
