Launching on Tuesday (9 May), the new campaign offers £99 deposits on all "Luxury" and "Essential" European river cruises throughout 2023.
The operator will also be waiving solo supplements on summer departures of Travelmarvel’s European river cruises and offering savings of up to 50% per person on select itineraries.
The best cabin upgrade and solo supplement offers apply to new bookings made between 9 May and 31 July, and for European river cruises departing between May and August 2023.
Brad Bennetts, head of sales and business development for APT and Travelmarvel, said: "This newly launched summer tactical gives our agent partners everything they need to convert business over the coming months.
"By adding outstanding value via best available cabin upgrades, solo supplement waivers and up to 50% savings, as well as removing barriers to booking with low £99 deposits, agents can tempt even the most hesitant clients to take a European river cruise this summer."
