Thirdly, the display screen in Roku guest mode is not customizable. The apps cannot be customized, there is no interactive slideshow with hotel information, and no way to display a personalized guest welcome message. A personalized display screen is a chance to greet guests, make them feel valued and welcomed, advertise local attractions, showcase hotel amenities, and give the guests the feeling they are staying in a high-tech, modern facility. The welcome screen is also a great opportunity to encourage guests to book again through a direct booking website.
