The only recommendation that I could make would be the Naval Air Station, but you have to be retired military, or DOD connected. With that said, we went on a drive through of many of the CG's in the Corpus area and could not honestly say we would stay at any of them.
Drive up the road 20 miles or so and look around the Aransas Pass area. It's a short distance from Corpus. Also look at the Rockport area.
Corpus CG's did not impress us except for the military Shields RV Park.

It is what it is, and then it is what you make of it.
