Hotel Bel-Air, Los Angeles
After a two-year, multi-million-dollar overhaul, this Hollywood Hills icon is wired with the latest tech to keep up with a demanding clientele that has ranged from Marilyn Monroe to Oprah.
Upon arrival, in-room check-in includes a tutorial by the bellman on the use of all guestroom gadgetry -- ensuring you don't freak out later about how to operate the smart toilet.
As you approach said throne -- aka the Neorest 600 -- its motion-activated lid opens automatically and features a control panel for flushing and other functions, like a seat heater and deodorizer. The bathroom also has heated floors and an in-mirror LED television.
Guests book massages or dinner reservations from in-room iPads -- pretty much the luxury hotel norm nowadays -- and there are Bang and Olufsen HD flatscreen TVs, smart lighting with mood settings and a touch-screen phone that lets you control everything from room temperature, lights and media to curtain height.

Yotel New York, New York
An homage to luxury airline travel, this Times Square hotel is unapologetically futuristic. White walls backlit in purple create an ultramodern atmosphere as you check in at touch-screen kiosks similar to those found at airports, only cooler.
Guestrooms (or "cabins") are decked out with purple mood lighting, near-silent heating and cooling systems, a Techno Wall fitted with a flat-screen LCD TV, lots of power points for laptops and other devices, Wi-Fi (included in room charge), an iPod or MP3 connection for playing music through the TV speakers and a motorized bed that expands to full size at the push of a button.
The hotel's tech de resistance is the world's first-ever robotic luggage handler. A 15-foot robotic arm towering in the lobby behind a glass window, the Yobot picks up your luggage and safely stores it in a wall of drawers before or after check-in.
No tip necessary.

Interactive reader boards with touch-screens fill the lobby and let you check everything from flight info to area attractions, news, weather, meetings and events.
