Got a late start the first day and after 50 miles we stayed at North Hero state park. The next day we rode 85 miles and got to montreal around 7 pm. We pretty much took route 2 all the way on the US side, crossed over at Rouses Point, NY and took 225 up through canada. Most of the route is flat, and there's a long bike path that goes along 225, and champlain bikeways will take you along route 2 (but it winds around and is a bit longer). Getting from the mainland into montreal is a bit tricky, I'm not even sure how we managed that... So you might want to have your escape route planned out a bit better if you're looking for an early start.
You should do it! It would be possible to do in one day but I'm not about to try it. Let me know if you have more questions.
