Parents of children aged three to 11 years old holidaying on the Oasis of the Seas ship are being encouraged to use the system so they’ll always know where their children are while on board.

The newly launched cruise liner is huge, has 16 decks and can carry up to 6,300 passengers.

All children on the ship must wear a wristband which has an electronic chip built in. The system is linked to a new on-board phone system called Royal Connect which also enables guests to keep in contact with each other and view all on-board activities.

The device costs £12 to hire for the duration of the cruise and, if it proves successful, will be introduced on all the cruise ships in the Royal Caribbean fleet.
