4. Mandarin Oriental
On its surface, Mirror looks like an ordinary piece of decor — but turn it on, and it transforms into an interactive fitness trainer that's now available in select Mandarin Oriental suites across the country, including in New York, Boston, Washington DC, and Miami. Guests can choose from a selection of in-room workouts that include cardio, strength, yoga, and even boxing. The camera and speakers are embedded and basically invisible, making this sleek fitness display as chic as the hotel's spa-like bathrooms. The brand also includes the Peloton bike in some of its higher-end suites, like the Mandarin Presidential Suite in Miami (#travelgoals).
