In this newly-created role, Halpin will oversee and grow TripAdvisor's vacation rentals operation, reporting directly to Stephen Kaufer, co-founder and CEO of TripAdvisor.

"I'm thrilled to have the opportunity to lead TripAdvisor's vacation rentals business," commented Halpin. "TripAdvisor is establishing itself as a leading and truly global player in this market, so it's a very exciting time to be joining the company. TripAdvisor has already formed some significant inventory partnerships and I look forward to expanding the vacation rental business even further."

As of November 2011, TripAdvisor exceeded 200,000 vacation rental property listings following the announcement of several partnership deals, including Interhome, Stayz Toprural and AKENA Technologies (which operates MediaVacances.com). TripAdvisor also lists properties from Holiday Lettings and FlipKey.
