Dan, Sounds like a good plan. We did that similar trip the first year.

I would suggest you take the boat tour through the Soo Locks. Go to the tour building first so you can reserve a time to come back.

Pictured Rock Boat Trip is an awesome ride. But be warned, it gets quite boring between leaving the dock and actually getting to the "Rocks". Some catch a nap on the ride back.
