With all this time to take advantage of, we are planing to do a mini trip to Fenelon Falls for that weekend. The working itinerary is to head to the bottom of Kirkfield Liftlock on Friday (3-4 hours from home) & spend the night there. Saturday we would continue on to Fenelon Falls Marina (2 hours travel time) & spend Saturday & Sunday nights there. Monday, we'd head back homeward & stay the night at one of the locks before Lake Simcoe & head home on Tuesday.
As well, you don't have to worry about going through the lock, as the marina is before the lock, right on Cameron Lake.
Here's some pics of the anticipated spots to whet your whistle;
