Weekends are always busier at popular tourist sites because kids and parents are free from school and work commitments.For shorter lines, fewer people, and better opportunities to interact and enjoy the attraction, stop by during the week.In many cases, you'll have the place all to yourself.To take this tip one step further, and guarantee a further reduction in crowds at your museum, gallery or tourism hot spot, head there after 2pm when visiting school groups will have returned to class.School trips during the week often hit attractions in the morning, but tend to depart in the early afternoon.
