A good place to start in an essay is with a thesis statement. In your case, you already seem to have one: "Honeymoon Tourism, Single Holidays and Gay Tourism can offer positive opportunities for the tourism industry." So, your next step would be to outline the specific ways in which "Honeymoon Tourism, Single Holidays and Gay Tourism" can be positive opportunities for the tourism industry. That will give you an introduction. Then, for each body paragraph, you would go back to your introduction and turn one of the points from your outline into a topic sentence. You would quote from your research to support your main points, then add a a concluding sentence at the end that ties your point back to your thesis. You would repeat this for each of your main points, until you had all of the body paragraphs you needed. Then, write a conclusion, and you'll have a complete draft you can post for further feedback.
