We are taking a 10 day trip to Grand Teton National Park and Yellowstone. We are a family of five with 2 adults and 3 boys, ages 21, 18, and 15. We are planning on flying into Jackson Hole Wyoming and flying out of Bozeman, Montana. We have booked 2 nights in Jackson, 1 night at the Old Faithful Inn, 3 nights in Canyon and 2 nights in Mammouth Springs. We still have a couple of nights up in the air. We would like your suggestions as to what to see and do in both parks. We want to do a whitewater rafting trip (suggestions on rafting companies), a horseback ride and some hiking. We also hope to drive the Chief Joseph Scenic Highway one of the days but aren't sure how long that would take and where and when it would make sense to do it. Also, is Cody Wyoming worth a roadtrip? Also, any recommendations for park guides or should we do it on our own. Thanks so much for your help!!
