I can not make a recommendation based on your preference. However, I have stayed (several weeks) at the San Antonio KOA, page 1401 of the 2006 Trailer Life Directory. The park is neat, clean and quiet. The sites are pull through 50 amp full hookups. There are sites with trees and no trees. There is a pool. The CG is in the North East area, mentioned in your OP. The CG is convenient to I10, I 410 and I35. I would stay there again. I was last there in April of 2006.
