Go where the day-trippers don't.Away from the headline sights it stays manageable all day. Save the marquee ones.

5pm+

Take the city back.Day-trippers leave by early evening — the same squares empty out and the light is better.

Need flexibility? The 16th–25th is the month's calmest stretch — the easiest window to move around in.
