Sudbury tourist attractions that failed to sign up for a promotional campaign missed out on a slice of £770,000, according to organisers.
The 14-week Curious County campaign – which ran earlier this year and was funded by sponsors – promoted activities, hotels and attractions in areas including Lavenham and Long Melford.
The scheme’s slogan attracted criticism from then-Sudbury mayor Jack Owen and was snubbed by Sudbury businesses, with not a single one signing up.
Visit Suffolk, the Curious County organiser, has claimed the project generated an additional £768,433 in visitor spending across the county, with Lavenham Guildhall and Lavenham Swan named as two of the beneficiaries.
Amanda Bond, Visit Suffolk brand manager, said: “The impact on the economy is incredibly pleasing.
“Businesses who did sponsor and get involved have greatly benefitted.”
She said Sudbury businesses would have the chance to get involved in another campaign next spring.
Mrs Bond said: “This will be a great chance for businesses who feel they may have missed out to be involved. Sudbury businesses will have that chance.”
