Spas are like oases here in this city where health consciousness is usually not a thing. Nearly every resort has one of these magical places, where people with crazy skills whisk you away and do things to you that, let's face it, you would never in a million years allow a complete stranger to do to you. Keep in mind that some resorts charge an additional facilities fee on top of your treatment cost even if you're a guest at the hotel. And if you're not a guest and you book a treatment, you may be shocked at what they charge you to just walk in the door. (Unless $100 doesn't shock you.) At least you can totally turn the dressing room Zen snacks into an all-you-can-eat experience. Cucumber water and dry organic granola. Mmmmm. Check out our tips and spa service definitions.
