There's SO much to do! Day trips to Doylestown (several museums, a nice place to walk around); Woodmere Art Museum and walking around in Chestnut Hill; some of the historical homes in Montomery & other counties, such as Hope Lodge, Pennsbury Manor, Peter Wentz Farmstead; walks through towns like Skippack; a visit to Zern's; factory tours like QVC, Herrs, Utz, and several pretzel ones in the Lancaster area; Lancaster; Hershey (include the cave just beyond the city); Gettysburg (with its new museum); York County (with a lot of factory tours); Lake Wallenpaupack area in the Poconos, and Route 6; Baltimore &/or Havre de Grace; Annapolis; Poughkeepsie (Culinary Institute, Vanderbilt Mansion, Roosevelt Mansion); and so on. So much to see and do! I would go on the Pa. Visitors' Bureau website and download or request information. Ditto re NJ, DE & MD, all areas for weekend road trips. I'd also get the AAA books and maps for these areas. VERY helpful. http://www.ushistory.org/ has some info, incl. re Hope Lodge.
