And Finally... The world's biggest ever cruise liner is five times the size of the Titanic

At 20 storeys high and 360 metres long, the £855million Oasis of the Seas is the world's largest ever cruise ship.

And yesterday the liner, operated by Royal Caribbean, dropped anchor in Southampton on its maiden voyage from Finland to Florida.

More like a floating city than a ship, it's home to 8,500 people and even has an open-air park planted with 12,000 real trees. There's a bar in the lift for a cheeky cocktail between decks, and champagne bars and restaurants galore.

Theatre-lovers can see Hairspray, the first full Broadway show to be performed at sea. While to keep the kids happy, there are theme parks and a non-alcoholic "mocktail bar".

The OTT liner officially goes into service next month. So, if the thought of a cruise on it floats your boat, here's what to expect...

6,360 Number of passengers, plus 2,160 crew

£1,364 Starting price for a nine-night Caribbean cruise
