Cruise secrets that have been revealed over the years have opened up the world of the cruise holiday.
From cruise crew parties to dirty cabins, many of the secrets may have been better to stay hidden.
Yet with the cruise industry continuing to grow as more Britons take to the seas for their holiday, there is still much that remains a mystery.
Express.co.uk spoke to Captain Tuvo from the ITV documentary “The Cruise” about some of the things he has learnt by being a captain onboard the Star Princess.
Captain Tuvo revealed to Express.co.uk: “My main priority is taking control of the steering of the ship and ensuring we get into every port safely and on time.
“Otherwise everyone runs the ship slightly differently.”
He explained how much walking it requires, with some of the larger cruise ships over 1,000 feet long.
He stated: “I like to manage by walking, so I start from the upper deck and walk all the others probably 6-7 times to make sure crew members and guests are happy.
“In a day I cover between 18,000 and 20,000 steps.”
The Star Princess, with over 3,100 guests, was featured in the documentary showing many of the passengers and cabin crew as they toured Alaska.
Captain Tuva explained how the hardest part of the job can be “docking under strenuous weather conditions”.
Many travellers may not realise that in bad weather conditions, certain destinations on the itinerary may have to be skipped.
Passengers could be entitled to compensation for the additional costs if this happens to them but it is often given back as cruise credit.
Cruise holidays are on the rise, something which Captain Tuvo credits to being able to “move from one place to the next without having to pack and unpack time and again”.
A record number of Britons went on a cruise holiday in 2017, with 1.9 million heading for a holiday on the sea, according to Cruise Lines International Association (CLIA).
Unsurprisingly, the Mediterranean is the most popular destination for its beautiful beaches and sunny climate.
The number of cruisers could exceed the record in 2018.
