The tour and cruise operator is putting more than 80 prizes up for grabs, which will also include spaces on a two-night sailing on Spirit of Discovery in July 2019.
Other prizes include designer handbags, tickets to see Rita Ora, an Apple iPad and iPhone, as well as experience days.
Iain Powell, Saga’s head of trade sales, said “This is a very exciting campaign for us and is the culmination of many months hard work from the team.
“Not only have we just launched our biggest-ever incentive, we have also just released our new-look customer and trade marketing, all of which supports agents to deliver more in the new year.
“We have a vast number of agents supporting us and therefore we wanted to offer more chances to win.”
Saga’s trade marketing has also been refreshed under the Saga More tagline.
All bookings made between December 27 and February 28, 2019, will be automatically entered into the draw, while those made via sagaagents.co.uk will count twice. Prizes will be awarded every week during the promotion.
