Hi. You will have no problem finding just what you're looking for, but you best book soon. Fourth of July week and the week leading up to it are some of the most popular weeks, and go fast.
The boardwalk is 2.5 miles long and the rides and arcades are located at the most southern end of the boardwalk by the inlet. But anywhere on the boardwalk is easily accesible to the rides by just jumping on the boardwalk tram that runs both ways up and down the boards, 7 days a week in the summer.
I suggest you check these realtors to find something you like:
