We did this over 2 weeks in 2000 with 2 kids, 10 & 8. The focus was on natural areas, historical areas, short hiking etc. So not sure if it fits what you'd want. We drove through Canada from Michigan, saw Niagara Falls, Toronto, then headed thru upstate New York(Lake Placid), Vermont, NH, Maine, Boston, Cape Cod, RI, CT. I think you need passports to get into Canada now. Some highlights besides the Falls: The Franconia Notch State Park area in NH. Interesting walks/hikes but the Old Man in the Mountain is gone now, though it wasn't all that much. Scenic drives. Mt. Washington in NH. Acadia National Park in Maine and the town of Bar Harbor next to it. The town is touristy but still interesting, the Park interesting, great views, hikes. We went on a lobster boat tour and they pull up lobster traps, except there's a law they can't pull up traps on Sunday. The Freedom trail in Boston is interesting, driving to Cape Cod etc. The Mystic Aquarium in CT was interesting. We enjoyed what we did very much though we had to keep in mind the attention span of kids that age so. You can google all these things and more for more info.
