Hi Josie80,you didn't specify a means of travel but if this helps;
approx 6-9 hrs on a coach depending on time of travel,you could check out greyhound
bus lines @ greyhound.com,30 -70 $usd I would guess.
However, if you are driving it's about 3 1/2 hrs to cape may [ last stop in NJ],then a
short trip on the ferry [ cape may-lewes ferry .com],then about an hour's drive from
there.We were there two years ago,great place.Have fun,JMAC
