Cruise secrets: Expert reveals the surprising thing you should never do on cruises

However, travellers should never underestimate the importance of getting back to the ship in time after these excursions.

Rob Gower, founder of travel website Dragonfly Traveller, told Express.co.uk: Don’t lose track of time when you are on your cruise ship especially when in port.

“Normally when your cruise ship docks at a port you get eight hours on land.”

He added: “If you do your own plans on shore and you are late back, the ship will not wait for you.”
