We stayed at the Niagara Falls North/Lewiston KOA in October 2006. It was possibly the worst KOA that we've ever stayed at. The spaces were small (couldn't walk between ours and our neighbor's slides), the crusher run needed to be redone as there were large tire ruts in the lots, outside our door to our picnic table was a lake when it rained, and finally we had to park our truck in the site behind us as the sites weren't long enough to handle a 38 footer and a TV.
On the brighter side, it was in a quiet area well off the main highways.
