Going on a road trip in June - will be doing highlights only, as time doesn't allow for more. Will be starting in Badlands, then Black Hills, Devil's Tower and in to YNP. Currently no reservations available inside the park and on a budget. Will be entering the park from the North Entrance. I will have 2 days, so have thought about staying in KOA in West Yellowstone at end of 1st night/beginning of day 2. After leaving lodging on day 2, will tour YNP and then need a place to stay, as day 3 will be Grand Teton. Again, issues with lodging. I am incredibly excited to see both these areas and wish I had more time. Am looking to stay outside the parks without a terrifying amount of backtracking. Need some advice on possible itineraries for YNP and I already know that I'm a little crazy for trying to fit so much in to so little, but it cannot be helped. After Grand Teton, will be headed east and back home.
