I think that the best social network to use in the tourism industry is Instagram, because it is used for a younger people, statistically the young people want to travel more than the rest of the population. It is easier promote products and services, you can pay for advertising, upload as photos and videos as you want and use hashtags, that consist in a word or phrase preceded by a hash mark used within a message to identify a keyword or topic of interest and facilitate a search for it , upload as photos and videos as you want, something really useful in the tourism industry because of the people always want to see the place where are going to go before travel. That is why I think instagram is the best social network to sell and promote a tourism company, business or shop.
