We plan to take our 4 granddchildren ages 11-16 to Niagara Falls the end of July. We aren't sure the best place to fly into. We do plan to go into Canada and see the falls from the Canadian side. We need to know where to fly into and rent a car to go into Canada, where to stay on the Canadian side, and what to do besides seeing the falls one day. Any help will be appreciated. A sample itinerary would be great! Thanks so much.
