NNJ area's such as Secaucus & the Meadowlands sports complex area are near major roads for those in both NNJ as well as NYC to come visit.

CNJ area's such as Edison & Woodbridge are convenient for those in central NJ and have access to a few highways for those that live in the northern part of the shore areas to come visit.

SNJ area's could include a place like Cherry Hill, which can be gotten to by those in the SJ & Philadelphia area's.

Those are just general suggestions for towns, where you seem to find interest is where I would look more closely at.  Good luck w/ your trip!
