A port-by-port reference for 19 of the most-visited cruise stops worldwide — whether the ship docks or tenders, how far the worthwhile sites sit from the pier, a plan that fits a 6–8 hour call, and what to skip when the clock is the real constraint. Built for cruise passengers with a fixed return time, not independent travelers planning their own schedule (see Day Trips for that, or Island Hopping Routes for a multi-day circuit across several islands on your own schedule).
The gauge on each card reads three bars for the ports whose own "watch the clock" line calls out real risk of a late return, two for the ordinary ones, and one where the page itself says the port is lower-risk. It is a reading of that line, not a separate rating — the line it came from sits at the bottom of the same card.
