Locked into a busy day? Here's the play.

–9am

Own the morning.The ships dock and unload mid-morning. The headline sights before nine are yours.

10–5

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.Ships sail by early evening and the squares empty out — the best hour of the day.

Need flexibility? The 5th–7th 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.
