TripAdvisor (TRIP -0.83%) continues to build its portfolio of Internet travel brands. The company has acquired Jetsetter.com, a Web destination it describes as a "leading members-only private sale site for hotel bookings." The terms of the acquisition were not and will not be disclosed.

TripAdvisor has actively enlarged its online presence, to the point where it now operates a host of online travel destinations. Many of these concentrate on particular niches in the market.

The Jetsetter.com acquisition is part of TripAdvisor's efforts to cover more exclusive niches. In the press release announcing the acquisition, the company quoted CEO Steve Kaufer as saying that "with Jetsetter and our own SniqueAway brand, we now have two leading travel private sale sites under one roof."
