We stayed on the US side at Four Mile State Park on a premium site on the water. We also had great seafood and homemade ice cream in Youngstown. NY. There was a wonderful view of the Toronto skyline at night. You get free parking in Fort Niagara State Park by staying there which was very interesting. I agree with everyone that the actual sightseeing of the falls is better on the Canadian side. We loved the view from the Skylon tower. We also loved going to Niagara on the Lake which is the most stunning town we have every seen. Also, If you like wine, the winery tours around Niagara on the Lake are great.
