We will be travelling with three children ages 7-14. We will arrive in Denver on Aug. 2. We plan to visit the Rocky Mountains National Park then drive from there to the Tetons and Yellowstone; then onto sights in Utah, then onto Phoeniz with a stop at the Grand Canyon. We will fly out from Phoenix on Aug. 12. Any tips, recommended things to see, places to stop and stay, places to eat, and suggested routes would be greatly appreciated!! We are coming from the east coast and have never travelled to this part of the country. Thanks!!!
