Mia Walmsley, of Footprint Travel, and Kate Holroyd, of Strawberry Holidays, released the first edition of "Beyond the Bookings: Marketing Success Planner" in 2021.
The duo described the guide as a "roaring success", which reportedly sold out twice to more than 500 agents.
The planner aims to help independent travel agents and consultants focus on and improve their marketing output.
Walmsley said more than 90% of previous buyers said they would buy the guide again if it was focussed on 2022.
"We’ve learned a lot over the last 12 months, and we’re putting it all into the 2022 edition of the planner," she added. "This year’s will be smaller, but with even more content specifically for the travel industry."
The guide was put on presale on 17 September and will be with agents by early December. The pair are currently approaching suppliers for their contribution and inclusion to make the journal "as comprehensive and practical as possible".
