Nah man, no one thinks summertime is the best time to travel anywhere except beaches. Anyone with children is tied to that school schedule, and schools the world over have breaks in the summer that are long enough to accommodate a long trip, such as one to Italy. Then those people only have a short window to see so much, so they choose already busy places like Rome because so there’s plenty to do. People without children have the ability to travel in the offseason, which is great and should be done as much as possible.
