The official hotel headquarters of the Raiders — M Resort Spa Casino in Henderson, Nevada — just got a multi-million dollar makeover and a brand-new tower that doubles the hotel’s number of rooms and suites. A grand opening celebration on Dec. 2 featured an extended fireworks display and a special performance by legendary rock band Jefferson Starship on the expansive pool deck to usher in the new era luxury for the casino and resort. The newly expanded meeting space and upgraded casino floor highlight a sophisticated design element inspired by water, wind, and sand.

“Our goal was to create an immersive, elevated casino experience that connects with our identity as a resort retreat,” says Vice President and General Manager, Hussain Mahrous. “These design upgrades celebrate the natural beauty of our desert location and signal what’s to come with the completion of our expansion.”

The Best Spas in Las Vegas

Enhanced lighting and upgraded fixtures exude a glamorous glow over the casino floor, which includes a re-imagined high-limit room, renovated table game furnishings, and improved flow throughout the casino floor. Augmenter by stellar dining at Anthony’s Steakhouse, fine Asian cuisine at Jayde, and Marinelli’s, guests can cozy up to a number of bars for beer or artisan cocktail with live music or catch big name entertainment at the hotel theater.

Lounge the day away at the Daydream Pool Club, or better yet, head to Spa Mio for a day of pampering and wellness. Featuring 16 treatment rooms and 23,000 square feet of space, Spa Mio is a warm and inviting spa that combines intimacy with excellence. Flanked by textured stone walls, warm woods, and colorful accents, Spa Mio is a local favorite for its welcoming staff and lush facilities, which includes a fully equipped gym overlooking the pool deck.

We had the opportunity to speak with Spa Manager Carissa Pyper about what makes Spa Mio so special.

Key Features: At Spa Mio, we’ve created a modern oasis where relaxation feels personal and effortless. Our hydrotherapy amenities — Jacuzzi, cool plunge, rain shower, steam, and sauna — set the tone for a truly restorative experience.

Guests love our clean, welcoming space and the genuine connections they build with our professional team from the reception staff, to the attendants and therapists. Whether it’s a solo escape or a fun group spa day, we focus on comfort, care, and mindfulness.

Insider Tips: What makes Spa Mio special is the way every guest instantly feels at home. Our team is incredibly skilled, but it’s their warmth and genuine care that keep people coming back year after year. We’ve created a clean, modern environment where groups can laugh, individuals can recharge, and everyone leaves feeling lighter.

One of the best-kept secrets of Spa Mio is that our most loyal guests always arrive a little early — not just to unwind but to enjoy our hydrotherapy options. Start with a warm soak in the jacuzzi to ease muscular tension, step into the cool plunge to wake up your circulation and finish with a rain shower to reset your senses.

Because our team values genuine connection, many of our therapists have built relationships with guest that span years. The atmosphere stays professional and warm — like being welcomed back into a place where everyone already knows how you like to relax.

Snacks and Refreshments: We love elevating the guest experience with thoughtful touches including our complimentary refreshment bar. Guests can enjoy infused water, a variety of fine teas, and light snacks such as trail mix and our fresh, in-house-made granola bars.

And of course, no visit is complete without our famous Pineapple Spritzer — a refreshing blend of cranberry, pineapple, and a hint of orange that our clients look forward to with every spa day.

Splurge Treatment: I like to think of myself as a Spa Connoisseur, so my ultimate splurge is truly a full-day, head-to-toe experience. That’s why I love our Besties & Bubbles package — it allows me to tailor the treatments to exactly what my body and mind need that day.

I might choose an 80-minute massage, a 50-minute organic facial, a pedicure, and a blowout — enjoying a complete sense of renewal from start to finish.

The added touches — a complimentary glass of champagne and the 25% package savings — make it the perfect way to treat yourself or a loved one to an indulgent spa day.

Customer Favorites: We’re fortunate to have many loyal local guests who visit Spa Mio for a wide range of services. Our salon team — stylists, barber, and nail technicians — continues to be a favorite, while our exceptional massage therapists and estheticians are known for delivering deeply personalized spa experiences.

One treatment that has truly become a standout is our Wellness Ritual Package, which includes a 50-minute signature massage paired with a 50-minute signature facial. Guests love it because it’s the perfect full-body reset and it’s also one of our most popular gift options for significant others, friends, and family.

Featured Products: We’re very intentional about the products and brands we choose to feature in our services. For our facials, we proudly use Eminence Organic Skin Care — their botanically rich, results-driven formulas align perfectly with our commitment to clean, sustainable wellness.

Our massage treatments incorporate Body Bliss aromatherapy oils, allowing us to customize each service with natural blends that support relaxation, balance, and rejuvenation.

In our salon, guests love the indulgent experience of LALICIOUS products for pedicures, as well as OSEA’s ocean-inspired, seaweed-based skincare, which delivers incredible hydration and nourishment. Every line we partner with is selected to elevate our treatments and enhance the guest experience from head to toe.
