Google is piloting the feature now at concierge desks at Caesars Palace (which is why we're here for the demo), the Dream Downtown in New York City and the Hyatt in San Francisco. The feature will be available first in smart displays with the Google Assistant built in. That includes Google's own Home Hub, a smart home device announced in October with a screen that shows you things like recipes and news updates. It also includes smart displays made by Google's partners, including Lenovo, JBL and LG. 

But Google wants to eventually bring it to other devices, including smartphones.
