Personally, I would drive around New York City
and get down toward Philadelphia
as soon as you can on the first day (or early on the second day). That's a long drive, but it'll be a lot more interesting from there.
Stop by Atlantic City
if you like to gamble, though it's no Vegas. But the main thing is get to the coast if you can. Assuming you and your boyfriend like beaches and you're on a budget, there are so many places you can stop.
Start at Virginia Beach
if you want, or take a little time to see the Outer Banks
like Kitty Hawk
. Just make sure you aren't crossing the bridge on a Saturday during peak season, it's backed up for miles.
Drive down to Wilmington
, a nice small town on the ocean, and Myrtle Beach
, then cross back over toward Atlanta
If you can spare even more time, try to get to Hilton Head Island
or Tybee Island
before you end your trip.
