Cruise port times: compare usable time ashore, not scheduled hours

Scheduled port hours overstate the time you'll actually spend ashore. A worked example with two invented itineraries shows how all-aboard times, tenders, clocks and travel from the pier change the comparison.

Two seven-night itineraries each stop at three ports. One lists 27 hours in port and the other lists 28. On paper, the second gives you an extra hour ashore. Once you account for when you can actually get off, how long it takes to reach what you came to see, and when you have to be back, the first gives you almost two hours more.

The two itineraries in this guide are invented. The ports, times, travel times and buffers are illustrative assumptions chosen to show the method. They aren’t real sailings or a description of any cruise line’s schedule. The line rules quoted are from Royal Caribbean’s and Celebrity’s own pages, checked on November 8, 2026.

Scheduled time and usable time are different numbers

An itinerary’s arrival and departure times tell you when the ship plans to be in port. They don’t tell you how long you’ll have at the place you want to visit. Four things come out of the scheduled window:

• The all-aboard time. You have to be back on board before the ship leaves. Royal Caribbean’s US FAQ on shore excursions says the all-aboard time is “generally” about 30 minutes before sailing, and that you should check it once on board, where it’s posted near the gangway (checked November 8, 2026).
• Getting off and back on. At a docked port you walk off. At a tender port you take a small boat, which adds waiting and travel at both ends.
• Distance from the pier. If the old town or beach is an hour away by road, two hours of your port day are spent in transit.
• Your own margin. Arriving back at the pier one minute before all-aboard isn’t a plan.

The same FAQ says the ship won’t wait for guests touring on their own. Royal Caribbean’s page on delayed shore excursions says the ship will wait if a tour booked through Royal Caribbean runs late, or the line will arrange your return to the ship if it can’t. That difference is worth knowing if you plan to tour independently at a port where your margin is thin (both checked November 8, 2026).

Tender ports cost time at both ends

Royal Caribbean’s accessibility and assistance page explains that at some ports the ship anchors offshore and guests go ashore by tender. It also says a ship scheduled to dock “can change to tendering,” that weather and sea conditions may prevent tendering, and that there’s no refund or credit for missed ports in those circumstances (checked November 8, 2026). The page lists ports that require tendering; check the list against your own itinerary, and confirm with the line for your sailing.

Celebrity’s own article on tender ports (last updated May 23, 2024, read November 8, 2026) says a tender ride can take from five to 20 minutes, that some ports use a tender-ticket system, that guests on Celebrity shore excursions get priority to disembark, and that guests are told when the last tender leaves the dock. It also notes that most tenders can’t carry mobility scooters. If you use a mobility device, a tender port may not be usable at all; ask the line before you choose the itinerary.

Which clock the times are on

A ship doesn’t always keep the time of the port it’s in. Royal Caribbean’s FAQ says shore excursion times are based on the ship’s time (checked November 8, 2026). That page doesn’t say which clock the published itinerary uses, so check how the times on your itinerary and in the line’s app are labeled, and listen for any announcement about the ship’s clock.

A one-hour difference doesn’t shorten your day if you convert correctly. It costs you the ship if you don’t. The example below shows how.

The worked example: two invented itineraries

For both itineraries, these assumptions apply. All are invented for the example:

• All-aboard is 30 minutes before the scheduled departure.
• At a docked port, you’re off the ship 30 minutes after arrival.
• At a tender port, you’re ashore 90 minutes after arrival, allowing for tickets, queues and the ride. The last tender back leaves shore 30 minutes before all-aboard.
• You want to be back at the pier or tender landing 30 minutes before the last moment you could make it.
• Travel times are each way, from the pier or landing to the one place you want to visit.

Itinerary A

Itinerary B

Itinerary B has one more scheduled hour, but Itinerary A gives 1 hour 50 minutes more at the places you came for.

Here’s how two of the rows are worked out.

Dunmore (docked). Off the ship at 7:30, then 75 minutes by road: at the old town by 8:45. All-aboard is 18:30, so you want to be at the pier by 18:00, which means leaving town at 16:45. That’s 8 hours, out of a 12-hour scheduled call. Two and a half hours of the day are spent on the road.

Fairport (tender). Ashore at 9:30, then 45 minutes: at the sight by 10:15. All-aboard is 17:30 and the last tender leaves shore at 17:00, so you want to be at the landing by 16:30 and leave the sight at 15:45. That’s 5 hours 30 minutes, out of 10 scheduled.

The other rows use the same steps. Birch Island, the other tender port, loses 3 hours 20 minutes of its 9 scheduled hours; Alder Bay, docked close to the sight, loses 2 hours.

The clock in the example

Suppose Elm Cay’s local time is one hour behind the ship’s clock, and the itinerary lists Elm Cay’s times in local time. Departure is 16:00 local, which is 17:00 on the ship. All-aboard is announced on board as 16:30, ship time.

If you read that 16:30 off your phone, set to local time, you’d plan to be back half an hour after the ship has sailed. Converted correctly, all-aboard is 15:30 local, which is what the table uses. Write each port’s all-aboard time down in the same clock your watch or phone will be showing ashore.

Scheduled isn’t guaranteed

Everything above starts from the published times, and those can change. Royal Caribbean’s US ticket contract lets the line cancel, advance, postpone or deviate from any scheduled port of call, and says it isn’t liable for refunds or compensation when it does, apart from the exceptions the contract sets out (checked November 8, 2026). A tender port can be skipped in bad weather, and a docked port can become a tender port. Treat a port day as planned, not promised, and don’t build a trip around a single port you can’t do without.

How to compare your own two itineraries

1. List each port with its scheduled arrival and departure, and note which clock the times are in.
2. Mark each port as docked or tender, using the line’s own information for your sailing.
3. For each port, choose the one place you most want to go and find the travel time from the pier or tender landing.
4. Work out the all-aboard time once you’re on board, and use your own margin before it. At tender ports, work back from the last tender.
5. Add up the time at the sights for each itinerary, and compare those totals rather than the scheduled hours.

If the totals are close, other things may decide it: a port that’s a tender port in one itinerary and docked in another, a port you’d miss most if it were skipped, or a long day you’d rather spend on board.
