My FI wants to take the kiddos somewhere with sledding, snow, etc. next month and put me in charge of figuring it out (isn't that always how it is, LOL?). He was thinking somewhere within a 1 hour drive of Seattle, if possible, since the babies hate the car and much more than that is really tough. Any ideas/recs? None of us ski, but sledding and such is good. Cheap is good... preferably no more than $250 per night, if possible.
