I am attempting to plan a week long trip to Yellowstone and GTNP this June for my family. I have 2 teenage daughters and my husband. I have lodging for 2 nights at OF Snow Lodge and 2 at Mammoth Hotel. We will be flying out of Atlanta. Some tentative sights are Cody, West Yellowstone Grizzly center, and Float trip on snake river. Would love any suggestions on airports, lodging, activities. We will fly in on Friday and leave the following sunday, so 8 full days. thanks!
