Hello, I'm new here and I'm looking for advice in planning a family (young kids) road trip from Seattle to Yellowstone and back, preferably a loop. So far, I'm thinking something like this:

Lake Coeur D'Alene
Glacier
(something in between maybe?)
Yellowstone
Grand Tetons
(and then I'm not sure what would be a good route home with some interesting, albeit anticlimatic, stops along the way)

I welcome advice and suggestions. We're hoping to take 2 weeks or so.

Thanks in advance!
