We are in the planning stages right now. I've never been, a few coworkers have but they are hotel people. I am taking the TC and my family loves the outdoors, animals and hiking. We are thinking early...
We too found that 3 days was a good plan and including Glacier NP, if possible, also is a grand plan. We have lots of maps and reading stuff about the areas we visit to keep our Grandkids busy and interested. Also Cody, WY with the Buffalo Bill Museum was a great spot for an overnight.
