Hotels are concentrated near the airport, along the waterfront, in the business district and in the Independence Park area. Wonderful bed-and-breakfasts and inns are scattered throughout Center City, as well. Philadelphia is always crowded with visitors at the usual vacation times, including New Year's Eve and Day, when thousands journey to the city to see the fabulously wacky Mummers Parade. The Pennsylvania Convention Center can draw thousands during big events, so it's wise to book hotel rooms well in advance.
