We are coming down in August to spend 4-5 days with our teenage grandchildren in early August. They live in Gonzales, Tx. We've looked at the San Antonio Riverwalk which we would enjoy, but they might get bored. We looking for a place on the Texas Gulf between Galveston and Corpus Christi. We would like to spend time relaxing by the shorline, in a hotel with a pool, and a few things to do in the area. We could drive to day time activities and come back in the evening. We are looking for suggestions. Thank you.
