Hi Olivia1976,
I am so jealous of you. I am familiar with the ICW. The ICW is most of the length of the entire Eastern Seaboard.One of my favorite place is the Gulf of Mexico, because there is really good fresh air. However, you should check a weather in Summer. A storm may hit to the area.
Also, here is links that help you.
