I have wanted to get to Yellowstone for ever, but as a boat kid on the east coast, this was just a dream. I wanted to take the kids, but never had enough vacation time.
Without kids, we got there this September. If you are going while the kids are out of school, it will be crowded. If you work SA for it, you will find out that it is a 5 plus day trip just to get there. It is worth it. In Spades - It is worth it. We took 9 days, but we also did a lot of museums along the way.
A lot will depend on how good you are a Wallydocking (Cabel's has dumps and there are three on the way). You really need to research this trip - Starting Now. If you have two drivers and can push, that will help, but there is still too much to see on the way there.
I wish you many boring miles of drive and hours of pure awe at the stops.
Matt
