Amazon is today introducing Alexa for Hospitality, a special version of the company’s voice assistant that will be distributed on an invitation basis to hotels, vacation rental spaces, and other locations starting today.
The Alexa experience will be customized and tailored to each individual hospitality location, so guests will be able to do things like order room service, request a housekeeping visit, or adjust room controls (thermostat, blinds, lights, etc.) using an Echo in their room. They can also ask location-specific questions such as what time the hotel pool closes or where the fitness center is.
