Are you ready for the holiday season? Are you excited about 2020 and a new decade too? In just two weeks, we are going to welcome a new year and, more importantly, a new decade. I hope everybody is celebrating the fruitful year of 2019 . In 2019, I shared a total of 24 discussions, if not counting this summary piece, covering the topics in food delivery, tech trends, customer loyalty, Airbnb, and other marketing issues. Looking ahead, I believe many of the events we discussed in 2019 will significantly affect the hospitality and tourism industry in the future. Through a review of what happened in 2019, we can get a good idea of what we can expect in 2020 in hospitality and tourism. Restaurant business and food delivery In 2019, we discussed two threads about the restaurant business and four threads regarding food delivery, making up 25% of the topics that we talked about in the year. Will those trends have continuous impacts on the restaurant business in 2020?
