Four Seasons Hotel Denver is ready to celebrate its first Halloween, and is offering guests some real treats.

This Halloween, Sunday, October 31, a massage, body treatment, facial, manicure or pedicure is a treat at the newly-open Spa at Four Seasons. As an added perk, guests can enjoy a 90-minute treatment for the price of a 60-minute treatment this Halloween Sunday. The Spa, which has a subtle gemstone theme based on the gemstone-named treatment rooms and several treatments that incorporate gemstones, also is allowing guests to “trick or treat” for gemstones. After any Spa treatment reserved on Halloween, guests can select from a bowl of shimmering gemstones and take one home as a Halloween treat. Spa staff can describe the healing powers of the stone that was selected.

Guests who reserve a minimum 60-minute treatment are given access to the Hotel’s state-of-the-art fitness centre, featuring TechnoGym equipment including treadmills, elliptical machines, stationery bikes, leg machines, lower back and abdominal machines, weight bench units, exercise balls and more. Complimentary valet parking is provided to all Spa guests who experience a minimum 60-minute treatment.

Also, at EDGE Bar, the celebrations start on Saturday night, October 30, with fun Halloween specials set to the “Playboy” theme. EDGE cocktail servers will wear bunny costumes, while EDGE bartenders will wear Hugh Hefner-inspired outfits. Guests can enjoy special Halloween cocktails such as Screaming Bunnies, White Russian Rabbits, and The Seven Deadly Sins. Halloween sushi rolls as well as decadent cupcakes—Red Velvet, Spider, and White Rabbit—will be served. A DJ will be spinning and Halloween Playboy Mansion footage will be projected on the EDGE back wall.
