My son is working for Raytheon on assignment at Wallops Island, VA, so we flew him down there as part of last week's east coast adventure. Wallops is right next to Chincoteague VA, which is a cute resort town with a nice beach. We stayed at a pretty nice waterfront hotel, and went for a walk on a beautiful beach.
The airport options are sort of limited-- if only Wallops Island was open to GA! I went to Salisbury MD this time, and previously went to Accomack VA. Neither is perfect-- Accomack is slightly more convenient but has no rental cars, while Salisbury, although further away, has all the amenities you'd expect.
A fun place to visit.
