Head down to the next exit (#0) and visit Cape May. Tons of things to do. Dozens of house and walking tours, plays, winery tours and tastings, an alpaca farm to visit, great restaurants, lovely streets for walking and bike riding. Visit the lighthouse, take a yoga class on the beach, climb the WWll tower. There's a brand new Nature Center to visit and CM is especially big in the fall for bird watching- there is a reserve there devoted to just this.
There will surely be some special events going on. There's usually some kind of an art reception at the Chalfonte- a must-see place, as well as other activities- fall is a HUGELY popular time there.
We've actually been on the beach as late as October. You just never know.
You can take the Cape May ferry from there across the Delaware Bay. Some of the boats have been renovated and are quite beautiful; sometimes there is music and a bar offered on board. Relax for the 70-minute ride. Once you get across, you can go outlet shopping in Delaware OR just stay on the boat and come back.
If thrift shopping is your thing, there's a nice new ARC in Wildwood by the ShopRite. There is also the boardwalk and the tram car. And there are some "doo wop" tours of the 50's architecture.
You can also head a few exits north and visit the gardens at Leaming's Run. Never done it but will one day.
Enjoy!
