Romain Baron outlines several trends in the hospitality industry for 2020: 1) Women-only services and products like gyms and hotels are growing in popularity. 2) Small, unique brands are preferred over local suppliers just for the sake of being local - the brands need to be genuinely better. 3) Sustainability is a major focus, with demands for palm-free, plastic-free, organic, and fair trade options as well as environmental protection. 4) Hotels need to provide much higher value for direct bookings rather than just price matching OTAs.
