Recommend the Canadian side if possible. We stayed at the Lundy's Lane KOA - not fancy and the sites are a bit on the snug side, but it was a good base from which to tour the area. We used a tour operator that ran excursions right from the CG. It was pricey, but parking alone the Niagara Falls area in very expensive. The tour included things like the Skylon Tower, Maid of the Mist, tour behind the Falls, etc. We also made a side trip to the locks on Welland Canal at St. Catherine's to watch some freighters go through. Very impressive.
