The experience of a guest in a hotel will radically change in the coming years due to digital guest experience tools. Hotel guests will be greeted by robots, check in with their smartphones, and be guided through the hotel by augmented reality and beacons. If something is missing in the room, a 3D printer will deliver the item. Nanotechnologies and biometric methods will also make their way into the hospitality industry, along with chatbots and holograms. Digital guest experience tools represent an investment area within the digital hotel value chain that should be considered and utilized by the hospitality sector. Björn Radde explains how the digital guest journey is evolving and describes the key digital guest experience tools for optimizing hotel stays, as well as their impact on guest satisfaction and revenue.
