Can't move the dates? How to avoid the worst crowds
- Need flexibility? The 16th–20th is the month's calmest stretch — the easiest window to move around in.
- On the busy days, the walk-up queues for the big sights are the biggest time-sink — a timed-entry ticket skips them, which is where a busy month is won or lost.
