@mark seifert , one thing to consider is that you can camp on either the ocean or bay side. The ocean side is obviously great because you're right on the water, but when we were up there a few weeks ago I would have personally preferred the bay side. It was incredibly windy on the ocean side, and there's no shelter from trees, brush, etc for the most part.
Bayside is MUCH calmer, with a lot more vegetation and shelter. However, once it gets real hot and humid the bayside is heavy with mosquitos. I imagine it wouldn't be too bad now.
Assateague is absolutely worth doing!
