!!!!
i have a family friend that is a travel agent and all she does is promo her stuff and deals on social media, especially IG and facebook. its great for IG, for example, cause you can post photos of the destinations, etc. and you can link websites to the posts too for example if you were promo-ing a specific cruise/trip. she also documents everywhere she travels too on social media, tags the places. social media will be your best friend here i think
