I would combine another excursion or two for the same trip, make it an all-day-er. We bundled the black river, Appleton rum distillery, and Y.S. falls, and stopped for some lunch somewhere in-between. Either find yourself a driver from the transportation section on this site, or a lot of hotels can set it up for you with a tour company. Yes, it was a long day, I think we were gone 11 to 12 hours, but while you're out that way might as well get a few locations in. I would recommend the private driver option; you can customize the trip as you go.
