We implemented an Alexa demo for an AirBnB property.  Guests can ask for location of amenities, issues inside the house, local recommendations etc.  The owner uses an owner portal to customize the welcome message, amenity, local recommendations, etc.

We use a QR code post inside a hotel room.  The guests scan the code to  receive hotel concierge services like food ordering and maid service in multi-languages.

We use a voice-enabled chatbot to serve tourists on the road for audio tours, common questions like where the restroom is.
