We went the last week in June. Honestly if the trips were not so expensive we would do another. Everything was extremely organized, and seamless. We had great weather. It only rained once, and that was in the middle of the night. The nights and mornings were very cool. We wore shorts and T-shirts in the day, but jeans a LS shirt and jacket were necessary at night. Our guides were outstanding. One was a former Yellowstone guide, the other was a guide at WDW for the special tours at Epcot.
