Westin Hotels & Resorts and Aromatherapy Associates have entered a global partnership to introduce signature branded experiences at all Heavenly Spas by Westin.

The partnership includes four signature treatments using uplifting essential oils and techniques based on how guests want to feel.

Additionally, Aromatherapy Associates will serve as the official retail partner for Heavenly Spa by Westin.

The foundation for the new Aromatherapy Associates experiences is the “How do you want to feel?” wellness wheel, developed specifically for Heavenly Spa by Westin. Spa therapists will use the guest’s response to that question to select essential oils, ranging from Relax to Renew – as well as techniques, music and recommendations to achieve results.

Based on research that shows people visit spas for psychological reasons in addition to physical ones, all of the signature treatments will have therapeutic properties with the aim of improving physical, mental and emotional well-being.

The Heavenly Spa by Westin footprint continues to expand globally, with 34 spas around the world in destinations ranging from Maui to Fiji, Cancun, Hyderabad and Beijing.

This year, Westin will add nine new Heavenly Spas including The Westin Resort Nusa Dua in Indonesia, The Westin Haikou in China and The Westin Singapore Marina Bay, which join the newly opened Westin Diplomat in Florida and The Westin Lagunamar Ocean Resort in Mexico.

Jeremy McCarthy, director of global spa development and operations for Starwood said: “By partnering with Aromatherapy Associates, Westin is able to provide its guests with an elevated spa experience that physically restores and emotionally uplifts, ensuring that they leave feeling better than when they arrived.”

Each Heavenly Spa will feature signature Aromatherapy Associates treatments as well as offerings customised to the individual property.
