The best bet is to look at three things to make the decision:
1. What are your skills, the things you are good at?
2. What do you enjoy; what are you passionate about?
3. What is the market demanding right now ?
My preference is usually for a service business, as the startup costs are lower and the margins higher. As you mention, tourism is a great entry-style business. So, too, are computer consulting, real estate and so on.
Hope this helps. Brad Sugars
