We are coming to CC in July. We will be staying in corpus at the navel lodge. I need advice on which beaches would be best to visit. I don't plan on spending time at any CC beaches. We don't want to spend time on the bay beaches. Should we go to North Padre, mustang Island, or PA? We will want bathrooms. I wasn't sure if the national park areas had bathroom facilities. ANy advice would be appreciated. Our only plans are to sun, build sand castles, and my daughter wants to boogie board. She is having withdrawls from our Florida trip.
