I haven't done it, but I did the 2012 Hudson Valley tour wth my 11-year-old, which was run by P&TNY as well. I spoke to many people on that tour who had also done the Erie tour; every single person thought that they were very, very well done.

I was extremely pleased as well. The rest stops were always well staffed and supplied, cue sheets were spot-on ( more important for the Hudson tour, since it's nearly impossible to get lost on the Erie Canal ;-) ), and all of the staff and volunteers were top-notch. I really can't recommend the group highly enough.
