Marriott is using their Aloft hotel in Boston to test both Alexa and Siri to determine which digital assistant customers prefer. In addition to the features mentioned, guests can control their television, lights, and room temperature with their voice. That will make turning on the air conditioner from bed much easier!
One thing customers should not anticipate is the devices being used as marketing tools. Users have reacted very negatively toward unexpected ads coming from their digital assistants. Therefore at this time hotels are using them as a way to enhance the guest experience rather than increase revenue.
