We have an excursion trip (not a necessary one) planned for this month. LCH to LAX, LAX to SEA, SEA to CHI, CHI to LAX, LAX to LCH. The only time we will leave the train/stations is SEA and CHI, just to sleep and wait for our next train. We just want to make a western long distance ride sometime before March. Now I'm getting concerned about the weather. Should we change the EB to the CZ? We would like about 10-11 days with as few hotel overnights as possible. We live in Louisiana, so we're not too familiar with winter weather. Thank you for any advice.
