It can be done. You’d better have some serious energy and a willing partner. I have friends who are a couple who have 2 young children. They make their living guiding. She was born into it, and they have a big ol’ boat. Everyone goes. And they have a Nanny and homeschool the kids. They charge enough to make it work successfully. They are wonderful neighbors. They make me tired just to look at them though. I couldn’t do it. Everyone is different.
