Locked into a busy day? Here's the play.
- The heaviest port day is Fri 4 Sep — 4 ships in at once. See the marquee sights on a lighter day, or be there for opening time.
- Need flexibility? The 26th–29th 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.
