Yeah just another huge vote on yes from me. Every summer we go on a houseboat trip down there. Be careful though..you'll be spoiled with the all day good water down there
It's painful to come back to Indiana after the trip is over. I don't think I've ever heard of Center Hill but I've heard that Cumberland lake is pretty much the same as Dale. Here's a link to lots of stuff for Dale including links to marinas. http://dalehollow.org/index.html
I highly recommend Wisdom Dock...where we went out of last year and will be again this summer. All the marinas are pretty good though.
