The 232-page booklet offers information on airlines, hotels, touring partners, car hire, cruise lines, excursions and more.
The brochure also includes details on 25 new hotels, 27 new day tours and attractions, 16 new touring and self-drive options and eight new cruise itineraries.
It also features Central and South America as a destination for the first time, including Argentina, Brazil, Chile, Costa Rica and Peru.
Gold Medal’s marketing director, Kerry Gallagher, said it is "critical" for agents to be "fully prepared and supported" in the build up to the peak period.
"We’re delighted to be contributing to that with this new brochure, which showcases our widest-ever range of product in one publication and features plenty of new hotels, tours and destinations with which agents can inspire their customers," she added.
"It’s especially exciting to be able to feature Central and South America for the first time, which remain relatively unknown to the British traveller."
