Every time we've camped in the sardine can CGs we've had issues with others. That said vote with your feet. Not every CG is like this. They each have a "personality" that is often dictated by how it's managed. So I'm pretty sure there are other places near Allentown that have better accommodations to your liking. Check 'em out on
Campground Reviews dot com. Also, you're only a couple of hours from there. Take a day trip and just inspect a bunch of them. Stop and ask some of the campers what they think of the place.
