I told my husband the dress code when we were planning our trip. I figured he could take care of his clothes while I packed mine and the 2 girls. Well, when we got there he didn't bring a jacket or a tie. He had lots of nice shirts, shorts and one pair of black dockers. When we were getting dressed and I said you can't wear that you have to dress up. He acted like he had never heard this part of the details. He was worried that he would look out of place with out a tie & jacket. Once we got in line to go in. We saw all types of ways people dressed. He was not out of place at all. Even though they ask for you to wear a jacket and tie, I felt like the atmosphere was still casual. People were still laughing and having fun. It wasn't real stiff feeling. If that makes sense
