We spend a week here and there in the valley and supposedly there are more than 500 parks. Amenities for us are simple, a nice club house where we can have happy hour, a gym with good weight equipment, showers, a warm pool and jacuzzi without too many restrictions (hours, use of plastic glassware).
My personal best pics are; Kenwood in La Feria, Victoria Palms (great clubhouse), Retama Village for the layout and use of bikes to go the birding center, and also Casa del Valle in Alamo (favorite).
Again, these are just my picks.
