Poulton, who joined TTC in January 2024 as National Accounts Manager, succeeds Kelly Walker, who left the group last month. She brings more than 20 years' industry experience to her hew role, following spells with Carnival UK and G Touring.
"Since being with the company, she has played a significant role in strengthening sales performance, account management and trade partner relationships, while increasingly stepping into a leadership role," said TTC.
It follows the group's decision to fold its Insight Vacations and Costsaver brands into Trafalgar, its flagship touring brand.
Kelly Jackson, TTC Tour Brands Managing Director and Senior Vice-President of Sales EMEA, said: "From the moment Polly joined TTC Tour Brands, her energy, work ethic and passion for our partners and our people really stood out.
"She has made significant contribution to our sales organisation over the past two-and-a-half years, not only through the relationships she has built and the commercial results she has helped deliver, but through the leadership she has increasingly shown within the team."
Jackson added: "Polly is someone who never stands still. She constantly challenges herself and looks for ways we can do better, making her a natural choice for this position.
"I have enormous confidence in her and could not be prouder to see her take this next step. With such an exciting period ahead for our brands, I know Polly is going to thrive in this role.”
Poulton said: I’m hugely grateful for the opportunities TTC Tour Brands has given me to learn, grow and develop, as well as the encouragement to bring my own ideas to the business.
"I’m excited to take everything I’ve learnt along the way into this next chapter, champion our trade partners, develop our people and play a part in what I genuinely believe is an exciting future for Trafalgar and Contiki."
