Ship-based game show, which sees twentysomethings head to the Mediterranean to hold a party on a lavish cruise liner and complete a series of physical and mental challenges in order to be crowned the most popular team. Setting sail from Barcelona, the ship, carrying 1,500 passengers, will sail the Med via Cannes, Corsica, party islands Ibiza and Palma, before heading back to Barcelona. The aim is to convince the other party-goers to vote for them in the week-long contest. At the end, the group that gets the most votes will win a luxury holiday to Bali.
Day two of the cruise liner-based game show sees Charlotte and Ed's teams competing to persuade their 1,500 fellow passengers that they are `the most fun'. As the ship sails from Cannes towards Ibiza, the teams choose stowaways to sabotage their rivals. There is also a competitive challenge to blag enough clothing to create suitable outfits for the Captain's White Party.
As the teams try to put their differences behind them, an explosive bust-up between Charlotte and Lewis rocks the boat. It's time for the notorious spray party as 1,500 passengers drench each other with champagne. A stowaway has no idea what he's letting himself in for as he tries to supervise his daughter, while a mother tries to settle scores for her own offspring. One team wins a fancy yacht ride around party island Ibiza.
As the group party on at several Ibiza hot spots, love brings enemies together while tearing friendships apart. And a granddad stowaway and an undercover boss get their groove on.
After a hard night partying, the gang wake up in Palma, Mallorca with new bed mates, putting friendships on the line. And it's time for the big vote as to who's the most fun.
