Can a Las Vegas hotel room actually make you feel better? The MGM Grand is about to find out. As part of the resort’s $160 million “Grand Renovation,” 42 of its 5,044 rooms are now “Stay Well” rooms, designed to reinvigorate road-weary travelers.

For an extra $30, here are the features you’ll get and the supposed benefits of each: melatonin-producing lighting (better sleep and quicker recovery from jet lag); electromagnetic field protection (sounder sleep); photo-catalytic coating on doorknobs, counters and other surfaces (fewer germs); dawn-simulator alarm clock (instead of waking up to a buzzer or an annoying DJ, you wake up to gradually increasing light); a HEPA-standard air purification system (fewer allergens and better overall air quality in your room); a water filtration system (less chlorine); vitamin C-infused shower (neutralizes chlorine, plus it sounds cool, right?).

The rooms also come stocked with healthy snacks and beverages (tofu sandwiches, anyone?), and you’ll have access to online wellness programs from the Cleveland Clinic as well as a “Stay Well” channel, featuring—who else?—Deepak Chopra.

It all sounds pretty awesome, and sure enough, the property is already seeing a “considerable amount” of bookings, according to Tim Kelly, vice president of hotel operations. The only question is, does any of this work? It’s certainly no seat-of-the-pants operation. The rooms are the brainchild of Delos, a New York real estate developer that worked for four years with both the Columbia University Medical Center and Cleveland Clinic to come up with the technology.

Kelly vouches for at least part of the experience. “I can tell you, being in the bathroom, you can absolutely feel the difference from the light components.”
