KOP is a much larger area surrounding two huge shopping malls with many more hotels and restaurants. But it has a reputation for vigorous LE activity but nonetheless many, many ladies visit there. Screening and discretion are advised.  

Plymouth Meeting also features a much smaller mall with less but adequate dining. Many ladies like the take out selection found the Whole Foods at the mall. There are about four nice business class hotels. Much fewer rumors of LE but I have heard of minor hotel harassment so screening and discretion are advised.

I have often played at PM and then drove to KOP for dinner. Legal Seafood is a favorite.

Screening is very important and something I do all the time.
