I am curious how you managed it. Did you get a roomette? Did you take long layovers along the way to break up the travel?
At the time, it was all coach from Philly to Chi. Left around 2:30 p.m. and arrived in Chi around 7:30 the next morning. From Chi to Seattle I got a one-person
room/coffin. Departed around 3:30 p.m. and arrived around 8 or 9 a.m. the second day. (I.e. leave on a Monday afternoon, arrive on Wednesday morning.)
We were allowed to get out and stretch the legs for 20 min or so in Minot, ND and in Havre, MT. Otherwise, I just read, watched movies in the observation
car and relaxed as the scenery sped by. The route skirts Glacier N.P. Acutally saw some mountain goats coming down from Marias Pass. The next
morning it was light out when we went through the Cascades. Amazing, especially when you are on some trestle hundreds of feet above some gorge
and cannot see the tracks below you. The second year I did not have a room from Chi. Just slept in a seat in the lower level. The seats are larger than
your average train seat and had leg support. I find the train relaxing, and I didn't have any time constraints. Running around Chi for half a day was also fun.
