You're a braver man that I, Dan!
We never go down there between Memorial Day and Labor day. Even better is to wait till early October, then it's a whole different atmosphere. Goes back to being the fishing place it was in the old days. Late September and early October is when Karen and I do our tent camping down on Assateague Island. It's much less crowded, and the bay side is still calm enough to explore by canoe. Crabbing on the bay side is great, very shallow water, easy to get aound by small boat.
When it's chilly enough to need a jacket, O.C. is a different place.
I think there's still a good all you can eat crab place up the road around 120th street or so. Huggins, Hutchens, something like that. We ate there last year, and it was good.
