Thanks for the suggestions. I guess I should have mentioned some of the places we have already done like Great Wolf Lodge, Gatlinburg, Newport Aquarium, Indianapolis and Nashville. DS and husband want to go back to Gatlinburg but I kind of want to do something different. I was thinking about Chattanooga but when I checked into it alot of the things you would do I do not think would be feasible with a baby like Ruby Falls and the caves. Has anyone stayed in one of the train cars in Chattanooga? So what are some fun things to do in St. Louis? I even considered Chicago but as one person mentioned I was concerned about the weather. Thanks for the input.
