No need to wear a swimming cap, no one will care. You can bring food, but no one will care if you don't leave it. There is a place to eat inside. If you don't bring it, you will regret it. If you're driving, you can play at both museums. If you are traveling in a group, it is recommended to choose a museum. You really don't have enough time. This is based on experience as you have just completed your tour. By the way, the Hawaiian pavilion is an indoor pool. Do you think I still need to bring sunscreen?
