Affordable dance classes for adults (18years old) in NJ ?
Look for Arthur Murray studios. There is one in my town, Highland Park NJ, of course that is too far I'm sure. It is very popular here.
Please post what price you are willing to pay. Check out your local park district.
We need more information. What type of dance classes are you looking for? Ballet, Ballroom, Bellydancing, or something else? What level of dance training have you had? For ballet, modern or possibly even jazz often there are open adult classes where you can purchase a class card of 10 or more classes paying as little as $10 a class in a decent school. Ballroom tends to be a set price without discounts.
