Center City hotels reported a 4.5 increase in visitors last year, registering a record 1.1 million room nights, and a record 78.2 percent occupancy rate, including 90 percent on Saturday nights, according to Visit Philadelphia, the tourism marketing organization.

The agency announced the annual statistics at an event Wednesday where it rolled out 2018 plans to strengthen its marketing focus on attracting foodies to the city. It includes a spring campaign to promote an overnight hotel package tied to dining, a video series in partnership with Bon Appétit magazine and the annual nominations announcement of the James Beard Foundation Awards for culinary excellence.

Visit Philadelphia also said its "With Love, Philadelphia XOXO" campaign would evolve into a "City of Brotherly Love" theme, and it plans to soon launch a "Homesick Philly" campaign aimed to attract former Philadelphians to visit or extend their stays.
