We are a planning a 3-day trip to Yellowstone Labor Day weekend 2014. We will be entering the park from the south entrance and I was able to get rooms at OF Inn night 1 and Canyon nights 2 and 3. I was considering canceling the first night in Canyon and staying in Gardiner on night 2 to save money (about $100) since we don't mind moving each night. Would this be ok or should I just keep my current in park reservation? Any ideas on a general itinerary for those days? And any guesses on how crowded the park will be on Labor Day weekend? Thanks!
