We are planning a visit in mid to late-September to Glacier, Grand Teton and Yellowstone National Parks. We plan to stay 3 full days in Glacier, 2 full days in Grand Teton and 3 full days in Yellowstone. We'd like to do some hiking, but nothing too difficult with too much of an elevation gain. Any itinerary recommendations, avoidances and recommendations on where to stay and eat would be greatly appreciated. Thank you.
