If you're going to be in Springfield, Mo. check out the FM Store it's not a quilt store but a fabric store and has some great prices. Also if you happen to go to Branson, about an hour from Springfield and possibly on your way to Arkansas there are several quilt stores. I especially like Quilts and Quilts, which is a 2016 featured shop in Quilt Sampler, according to their website. Love that shop.
Also...in Ozark, Mo. There is a great place to eat called Lambert's (not far from Springfield) put your name on the waiting list and then walk to Sew Simple Quilt Shoppe while you wait. Lovely little shop. A neat little cheese shop is next to that if you have a long wait.
Hope you have a great time!
