We usually stay inland near Mission. It isn't windy there. Last winter we tried Benson Palm outside the birding center. Very nice park. We tried Harlingen one year but too windy.(Tropic Winds takes Thousand Trails if you are a member) Safest place to cross into Mexico is at Weslaco into Neuvo Progresso MX. We didn't like Brownsville, very poor area, dusty and windy. The beach at Padre is nice for a visit. We only do TX every 3 years as we still like Florida. Next time we may try PA, we also like San Antonio but it is colder than the valley. Try several places, most parks have openings for short term also some take Passport America for short stays so you can try the park.
