I am planning our family vacation and was thinking about renting houseboat on Dale Hollow or Cumberland. We normally rent a cabin in Northern MI, but thought we would go south this year. Does anyone have a preference? Can anyone give some recommendations for some good outfits to deal with down there? What should I look for? I am also interested in knowing if there are any land based things to see. My wife is good natured and goes on the fishing/boating trips, but I would like to be able to offer her something too. TIA for your help. I have three boys 12, 17, and 20.
