You can go to Philly lots of stuff there to do and see less than 3 hours driving (Liberty Bell, Franklin Institute, Independecnce Hall etc)
Over shabbos with a Minyan in a motel is tough almost anywhere you go because most jewish areas are not in the tourist areas. There is actually in philly the second oldest congreation in the US Congregation Mikvah Israel (only the Spanish and Portgese Synagouge in manhattan is old) It dates from before the revolutionary war
