With a small group and a relaxed itinerary, the tour guide was very attentive, checking in on the tourists' progress. Instead of going to an outlet mall, we visited a large shopping mall in Syracuse with restaurants, clothing stores, IKEA, etc., enjoying free time. The frozen Niagara Falls was also beautiful. I'd like to see different scenery in the summer next time. The entire tour was in English, so I recommend having some basic English skills to listen to the guide's explanations of the sights and then using GPS to look up additional information.
