My friend and I are taking a roadtrip from Indiana to Utah to visit family. We want to take 3 or 4 days to get there. We are planning on taking I-70 as I have heard there is a lot to see and do. We will both have our children with us so any suggestions of campgrounds with swimming pools, playgrounds, etc would be greatly appreciated. We plan on stopping in St. Louis to see the arch. Is there anything else there that would be fun for kids (they are all under 6)? We found a campground in Kingdom City MO (6 hours first day). Between there and Denver we aren't sure where to stop. Maybe somewhere mid-Kansas. Also what should we go see in Kansas? We have both been to Denver but stayed with friends who no longer live there. Where is a good place to stay near Denver? We would like to camp to save money. Any suggestions would be very helpful.

Thanks!
