If I were in your shoes I would be thinking about this as a hobby and not as a full-time gig. After reading your post, our friend Rold came to mind. Rolf is great at what he does, because he is passionate about the BMW brand, and he enjoys sharing his BMW experience with others who share the passion. The added income is a bonus for Rolf. I agree with Tom and others who have pointed out the challenges of competing in a hospitality market that includes B&B's that have existed for decades. Maybe I'm being overly practical, but it seems to me that if you make it a hobby (with the potential to be something more) you will enjoy it more without having to set high risk income expectations for your family. My two cents...
