Dear Destinations: IAPCO Campaign launches to highlight the value Accredited PCOs bring to destinations and policy makers
Unlocking Excellence continues with the launch of Dear Destinations, a campaign speaking directly to convention bureaux, venues, government agencies and destination leaders about the power of meetings and conferences to drive economic, social and cultural outcomes for cities.
Dear Destinations and Policymakers,
Destinations that lead globally don’t wait for opportunities; they position themselves to secure them.
The world’s leading destinations partner with IAPCO members to secure and deliver conferences that drive economic growth, strengthen industries, and create lasting impact.
A strong pipeline of global events is confirmed for the coming years – many still to secure a destination or venue. These are real events, real budgets, real opportunities, creating a valuable opportunity for destination leaders and policymakers to engage early and influence outcomes for their city.
With rigorous accreditation standards and global expertise, IAPCO connects destinations to opportunity, helping them turn potential into long-term impact.
