I grew up in NJ so I know that there are a ton of Things to do in New Jersey. You could go to one of the all night diners that are all over the state, or head on over to Seaside Heights, or Wildwood if you are looking for an amusement park on the beach. If you are in northern NJ then you may want to just go to the Keansberg amusement park instead of traveling all the way south for something like Wildwood, though Morey’s Piers is a great place for a New Jersey Vacation.
Wildwood has a lot of stuff that happens every year, this year the Radio Disney Summer Concert series will be appearing there. Besides that though, Wildwood events are known throughout the state, bringing people down no matter how far north you live. A lot of the Wildwood nj hotels are packed all summer, so if you are thinking about going then you might want to book already.
Wildwood is also the place that seniors go when Prom lets out, that is kind of the unofficial start to the Wildwood vacation season, I think that high school graduates go down there too, but I am not too sure on that one. After I graduated all I wanted to do was relax, not go down partying. That was for the next night.
