Trying to drive more than 2100 miles in under three days is unwise, unsafe, and frankly nearly impossible. You should be aware that professional long-haul truckers are prohibited by law from trying such an endeavor because incident after incident and study after study have shown drives of such length (and perforce limited sleep) result in too many fatal accidents. If you need to be in Chicago sooner, then you need to leave Seattle sooner. 2130 miles requires a minimum of three and a half days to be driven safely. Not to mention that even if you do pull it off, you'll be so exhausted that you will be in no shape to enjoy whatever it is you rushed to Chicago for.
