Looking for group camping spots within about 3-4 hours of New Jersey

Hi all! Every year I organize a camping trip with a bunch of friends. It has continued to grow and now we generally have about 30 or so people who join us. Looking for a place within a reasonable drive which could be CT, NY, NJ, PA, DE, or MD really. We need a big spot, preferably with trees around and definitely a bonus if there is a nearby swimming feature. Open to any suggestions really but alcohol must be permitted; we can get a little loud but always stay respectful. Any suggestions are welcome! Thank you!
