From megaships to onboard kennels, we look at what's new on the high seas.
High-tech Oasis
It's a big year for Royal Caribbean, which launches the world's largest cruise ship, Harmony of the Seas, in April. The Oasis-class ship, which weighs a hefty 225,282 tonnes, will span 16 decks, carrying a staggering 5479 guests at double occupancy in 2747 staterooms.
Harmony will have similar "neighbourhoods" to the company's other vessels and will have two FlowRider surf simulators, a rock-climbing wall, mini-golf course, a bar with robotic bar tenders, and a water park with four waterslides, including the 10-storey Ultimate Abyss.
The ship will also feature Royal Caribbean's latest tech innovations, including the fastest internet connection at sea capable of streaming video and sharing pictures on social media, as well as RFID wristbands for guests, which can be used to open stateroom doors and wirelessly make onboard purchases; and special personal assistants called "royal 19-02-2016 05:00:00genies".

Harmony of the Seas will homeport at Barcelona for its first season and sail a round-trip, seven-night Western Mediterranean itinerary.
The cruise line is bringing megaship Ovation of the Seas to New Zealand in December. She'll start in Dunedin and make her way up the east coast, and will be the largest cruise ship to be based in the region.
Key features include an iFly skydiving simulator and a North Star mechanical viewing platform that suspends guests 90m above the ocean in a capsule.
Cunard's Queen Mary 2 is being renovated, adding 15 staterooms for solo travellers and more onboard kennels for those who can't bear to leave their dogs and cats behind. There's even a special recreation area for the pampered pets, with fire hydrants and lamp posts for the pups.
