K.S.
Stay in Niagara-on-the-Lake, Ontario, Canada, and do day trips to the falls. It is a quaint town one Lake Ontario with the Shaw Festival, horse carriage rides and delicious food. There are vineyards in the area as well that have lodgings, and the area is conducive to bicycling. It also is where at least one boat ride to the falls originates. It's a simple two-lane drive to the falls. Niagara Falls is a tourist trap. You will not regret staying a bit out of town.
And make sure you get to the Canadian side. The view of the falls is better from that side.
