The line welcomed more than 100 homeworkers, cruise specialists, consortia members and high street agents as part of the training initiative.
Delegates were able to experience the Quantum-class ship and took part in a full day of training, which included seminars on the Royal Caribbean brand, guest experience and onboard offerings.
The first seminar sailed from Southampton to Liverpool on a two-night cruise and the second departed from Liverpool for a three-night voyage back to Southampton.
The seminars concluded with agents building their own ‘perfect day’ for one of ten guests, with the winners awarded the prize of dining in restaurants Chops Grille and Wonderland.
Torey Kings-Hodkin, head of UK sales for Royal Caribbean, said: "Anthem is much loved by the UK trade and we are delighted to have welcomed so many agents back onboard at the end of her very successful domestic season."
