The line will pick the winning business based on whether it has secured high value bookings, showcased Ambassador offers in its window displays or in social media posts and increased its sales overall this month.
The winning agency will receive a staff room makeover to create their very own Ambassador Lounge featuring new seating, a coffee machine, a kettle, a toaster, a microwave and an air fryer.
Plus, the agency will also receive a new fridge filled with goodies, new crockery and cutlery as well as an Ambassador noticeboard and "other branded touches to make it feel like home".
Members of the Ambassador Trade Team will deliver the goods to the winning agency and help set up the staff room followed by drinks and a takeaway to celebrate.
Love2shop vouchers worth between £15 and £100 will be awarded to individual agents as part of the incentive which finishes on 30 September.
Furthermore, the line has confirmed agencies or agents don't need to formally enter the incentive. It added: "The Ambassador Trade Team will ensure that any agents that they see going ‘above and beyond’ are in the running."
Karen Cameron, interim head of trade at Ambassador Cruise Line, said: “Our valued trade partners are key to our success and the new We Sea You incentive is all about showing them our gratitude for their ongoing support of the Ambassador brand.
“Every time agents go above and beyond this month, they will be in with a chance to win one of the fabulous prizes on offer."
She added: "With National Travel Agent Day set to see the trade celebrated this month, this incentive is our way of recognising all that they do for us – we at Ambassador see you, we celebrate you and we reward you.”
Earlier this year, the cruise line opted to remove multi-generational cruises from its new itinerary programme following customer feedback.
Cameron told TTG at the time: "It's a change but not a huge one."
