What do people who living in north want? Exactly, go to the south and swim on a beach under the sun. It is possible to create as a business an artificial beach! It is basically an huge building like an hangar, with sand, sun and water inside of it. Create artificial small "sea" using a swimming pool technologies. Place ultraviolet light at a ceiling as the sun. Place an bar with drinks inside of the hangar. Place a sun loungers there. And so on.
In north countries it would be like local "heaven", where people could chill and swim as if they are in Africa.
