Start with the difference that trips up many passengers: all-aboard is earlier than the published departure, often by 30 to 60 minutes. Every plan should be built around all-aboard, not the sailing time.
For a city day, being back at the terminal 45 to 60 minutes before all-aboard is comfortable, because you are always within a short walk of the ship. Central Messina's compactness is a genuine safety net.
For Taormina, add margin for the coastal drive and any traffic. For Etna, add more still: the volcano is farther, higher and more weather-dependent, and the single road corridor can slow at busy times. Organised tours plan this for you; independent travellers carry the risk themselves.
If something slips, contact the ship's port agent — the number is on your daily programme — rather than assuming the ship will wait. Independent passengers are responsible for making it back, which is the strongest argument for a generous buffer.
Highlights
- All-aboard is earlier than published departure
- 45–60 minute buffer for a compact city day
- Larger margins for Taormina and, especially, Etna
- Port agent contact as your fallback
Tips
- Plan every day around all-aboard, not departure
- Note the port agent number from your daily programme
- Give inland and volcano days the largest buffers
