For San Antonio - we have always stayed at the KOA.
Travelers Village looks nice and is in a good location but we have never stayed there.
If you search this forum I think some folks have recommended Braunig Lake RV which is southeast of town.

We have not stayed at any places in Corpus. We have stayed at several at Port Aransas and Aransas Pass/Rockport.
Gulf Waters is very nice. Stayed there 15 yrs ago with dogs and a kid and came away thinking they had lots-LOTS of rules and we felt a bit out of place...but it's a very nice place.
We have stayed at Pioneer and Marina Beach (now called LaFite's Hideaway) most often.
Port A RV, Tropic Island, Island RV, Surfside all look nice but we have never stayed there.
There are lots of nice places in Aransas Pass and Rockport but the only one we have stayed at is Drifters and it's a good one!
