The Jones Beach Arena is located at the end of Wantagh Parkway. It is situated right on the bay just across from the ocean. The arena is about 3 miles from the nearest town. I would suggest looking at the Ecnolodge in Hicksville, NY. It is located right next to the Wantagh Parkway and offers a low rate. It is about 10 Miles from the Arena and Taxi Service should not be a problem. More Hotels are located in Farmingdale, NY which is closer to the arena. They are the Courtyard by Marriot and some sort of Suite Hotel. The travel time to the Arena would be about 15 Minutes from there and there are plenty of restuarants nearby the Farmingdale Hotels.
Jones Beach is a collection of Beaches, which is one of the nicest complex's ever created. Where the arena is is serviced by Fields 4 and Fields 5 which offers a Snack Food Places, a Band Shell, Pitch and Putt Golf, Volleyball, Shuffleboard, and More. Most of this is closed after Labor Day, but the boardwalk remains open. In September is the feast of San Genero in Little Itlay ( a short train ride and Subway ride ) in lower manhattan. Some of the best eating can be had there during the week of the feast and it is one of the safest places due to some well connected people watching over the feast. A possible car trip to the Long Island North shore one can see the gold coast mansions of the Great Gatsby Era. The Old Westbury Botanical Gardens is one of these. Riverhead has a Oyster Festival or a Polish festival around this time. A trip to freeport where there are several Seafood places that serve fresh fish and Shell fish. That is located on the Woodcleff Canal.
