Not so long ago, if you were exploring Philly after sunset, you were probably up to no good. These days, the Avenue of the Arts (S. Broad St. between Market and Pine sts.), Rittenhouse Square, Old City, and Northern Liberties come to life as the hour grows later and there are plenty of fun ways to occupy yourself.
For complete listings of what's going on and week-of discounts (called "Philly Fun Savers"), visit the Greater Philadelphia Cultural Alliance listings website, Philly Fun Guide at www.phillyfunguide.com or call tel. 215/557-7811. Another all-inclusive website, www.gophila.com, offers a marvelous overview of Philadelphia's cultural landscape.
For commercial attractions such as large concerts, Ticketmaster (tel. 215/336-2000; www.ticketmaster.com) is your best bet. Local ticket brokers such as the Philadelphia Ticket Office, 1500 Locust St. (tel. 215/735-1903 or 215/545-1527), or Ticket Warehouse (tel. 888/252-8499; www.ticketwarehouse.com) are also reliable. Out-of-state brokers may have better selections, though their prices could be exorbitant.
