Mutt, I agree with what ksjc posted. Although it has been years since I attended FSI Wilmington*, the biggest problem you will be faced with, is boredom. From what ksjc posted, it looks like not much has changed.
There are, or were, a couple of really good restaurants in the area and there is one that is north on the bay that leads to Philly that is right on the water. When ever a large ship goes by the restaurant, the lights are dimmed and name, destination of the ship is announced. But as I inferred, I don't know if it or the other places are still open.
So renting a car is mandatory and yes, Philly is the closest international airport.
* To tell you how long ago it has been, I attended Jet Commander and Westwind training there. So it has been a long time ago. The last time was in 1982 I believe.
Oh, if you can say, what aircraft are going for?
