If you can only do 1 mtn, make it Baker. It's only 1 additional hr on the road each way from Seattle vs. Stevens/Crystal. For a single trip during your vacation, it'll be worth it. For the 2nd day, either of the other 2 aforementioned mtns would be great, just depends on which mtn gets the snow while you're here.
