My family and I will be taking a road trip to Atlanta this summer and I am not sure what the best routes are. Got two different routes online - through Iowa to Missouri and through Chicago to Indiana. I need help with the best option, please. Also, where is a good overnight city to lodge half way as we plan on a two day trip each way. How can we keep three young kids (10, 8 and 6) entertained along the way? We are also on a tight budget. Thank you!
