We are planning to go to Glacier National Park from Seattle (we are flying to Seattle from Detroit). The whole family is going. I am in two minds about doing Yellowstone or Glacier National Park, or both. We have only 5 days to do the trip, so I was thinking of only doing one. The kids are little (my son's 9 and daughter 5), and I want them to see real Nature, and hopefully some clear night sky and wildlife. Since this forum seems to have folks who have been to both parks, I wanted to get some advice! Best regards, Nikhil
