I am planning a two-day trip to Yellowstone National Park and am looking for suggestions on what to do and see during my stay. I am especially interested in activities that will allow me to get the most out of my time there. I would love to hear from people who have been to Yellowstone and can provide me with advice on the best places to visit, things to do, and any other tips that could help me make the most of my trip. Any advice would be greatly appreciated!
