Our family (me & my husband and our kids, 6, 7, 8, and 16 years old, our 17 year old nephew, my mother and father-in-law, 2 sisters-in-law, and a family friend) will be going to Chattanooga on June 21. We will be staying until Sat., June 24. We are planning on visiting Lake Winnie on Friday, but that is the only thing planned. My father-in-law and my sister-in-law are handicapped, so we need to do things that are accesible for them. We really want to go to Rock City, the Aquarium, I-Max, maybe the zoo. Does anyone have any ideas? What are some must-sees while we are there? Thanks in advance for your replies.
