A handful of agencies were asked to pitch last week in the US, with a number of top UK-based agency figures flying out for the review.
The account is centred on growing the Hilton brand internationally, with a focus on developing economies.
Hilton is understood to be looking to markets such as Asia (specifically China) and Latin America to drive revenue growth and is looking for an agency with a global footprint and strength in these jurisdictions.
The brief is thought to be worth a substantial seven-figure sum in US dollars.
