It's a sign of things to come when the first question you're asked on arrival is, 'How do you like your margarita?'
Every room here has an ocean view, open fire and infinity plunge pool where you can enjoy your complimentary afternoon Corona, guacamole and chips.
Spend evenings stargazing with your in-room telescope or with the help of the resident astronomer. Similarly celestial, the spa treatments reflect the lunar cycle.
With your own PA on call, you needn't leave your room, but a private beach dinner can be arranged, or you can pick your own seafood to be grilled above the waves at El Farallón restaurant.
There are Mexican cookery classes and tequila tastings, and if the ample alcohol section at breakfast seems indulgent, as our waiter said, 'What? You're in Mexico!'
WOW FACTOR: Spotting whales from your plunge pool or the window of your rainforest shower.
