From the West Side of Washington, Pullman Washington is about 6 hrs and from the Cle Elum area it is about 3.5 depending on how many restroom stops you make :) (and how much you speed) Once you reach Othello, there are no more places to stop for gas or food until you reach Colfax and there is about an hour and fourty minutes in between so plan your stops accordingly.  

If you will need accomadations, contact the bride and groom immediately and we may be able to find someone's home for you to sleep in.  Since our wedding falls on the same weekend as University of Idaho graduation, there are no open hotels in the area.  You will need to book a room either in Spokane (hour and twenty minutes North of Pullman) or Lewisiton or Clarkston (fourty-five minutes to an hour South of Pullman).  We are extremely sorry for this inconvenience but please let us know if you have to stay in a distant hotel so that we can show our appreciation.  If you plan to drive home the night of, this may or may not be difficult for some people because the wedding should be over at about 8pm, however you may leave earlier if you need.
