There is an old KOA in Jackson and it has river tours etc. It would be a good place to get into and day trip out of for the Tetons. Jackson is also the home of the National Elk Refuge and has a great visitor center which is taken slowly is an easy couple hours to take in. The lakes around the tetons are great and nice drives. Too many folks go to yellowstone for us and the roads are always full. East of yellowstone is cody and the buffalo bill museum. South of it is Thermopolis and a great mineral hot spring place to visit with water slides etc for kids. Once back in utah go to gobblin or kodachrome state parks, we are planning to visit them this summer, never been to either. So work your way back to lv from there, 2 weeks is quit short for long tours as noted, a lot of driving.
Look at a large usa map as in an atlass and see how to plan some stops rather than using the computer stuff, makes it easier to visualize distances, than can look at the state maps for reference.
