Sailings starting at £50 a night are being offered to agents in an Ambassador Cruise Line trade concession scheme.
Agents are also eligible for a 15% discount on any drinks package, plus 25% off port parking.
The offer is valid for cruises of up to 15 nights and covers Ambience and second ship Ambition which is due to join the fleet in May.
Concessions are limited to ten cabins per sailing, on a first-come first-served basis, with agents able to make a maximum of one concession booking a year.
To be eligible, agents need to have made at least one booking with Ambassador and show proof of employment by providing their Abta number.
Head of distribution Nicola Harper said: “Our valued trade partners continue to be a priority for us. Following the success of the agent concession programme last year, we wanted to continue to give agents the opportunity to sail on our ships and learn about the Ambassador brand.
“Having agents immerse themselves in our product offering is integral to support their promotion of Ambassador to their clients.”
