Hi! My husband, 2 teen daughters, and I will be driving to a family wedding in Eugene, OR in July. We have about 2 weeks and were considering driving the northern route to Mt. Rushmore and Yellowstone before landing in Portland OR for a day before the wedding in Eugene (2 hrs. away). None of us are the nature-hiking types, but we do like history/landmarks (loved Gettysburg!), so Custer Battlefield, Rushmore, and Crazy Horse are all on our to-do list. We love shopping, unusual/fun/foodie places to eat, and interesting sites to photograph (not nature). We know Chicago well so will probably drive through. If anyone can suggest places to stop, particularly HIlton properties (Hampton Inns, Hilton, Hilton Garden Inns, etc.), that would be great, as well as must-see stops. Thanks so much!
