While I have never driven from Long Island (Central Nassau) to WDW, I know many people who have driven to WDW or other points in Florida. Depending upon the traffic, your origin on Long Island, and the number of stops you make, it will take you anywhere from 18-24 hours to drive to Walt Disney World. If you stop for the night, North or South Carolina are best as they are halfway between NY and FL. From what I heard, the long stretches of I-95 can get dull, but there are interesting places to stop, such as Williamsburg, VA and Savannah, GA. In NJ, DE, and MD there are service areas with fuel, food, and good facilities to help you take a break if needed. Getting from Long Island to WDW: take a highway that will hook you up with the Verrazano Bridge (I-278) and take it to Staten Island. You will pass through Staten Island on the Staten Island Expressway (I-278) and cross into NJ via the Goethals Bridge (I-278). Exit south onto the NJ Turnpike and take it to the Delaware Memorial Bridge into DE where you will hook up with I-95 south. Then, you will take I-95 south through DE, MD, VA, NC, SC, GA, and FL to I-4 west towards Tampa. Finally,
take I-4 for about 70 miles and watch for the exit for the appropriate Orlando and/or Disney
destination. Also, gas up in NJ, VA, and GA if possible as gas prices are lower. I am glad that you
are road tripping and I hope that you have a magical vacation!
