I have some questions regarding lower level Coach seating, and I hope some of you can help me with this, as I am now preparing for my fall trip to Seattle. I am wondering how is the ride in lower Coach on a cross-country trip of several days? I am in my mid-60's, and would love having the restrooms on the same level as my seat. Would I need doctor's verification to reserve such a seat? And how crowded is the lower level in Fall and Winter? How is the visibility of the scenery on the lower level? Are there 120V plug-ins at the seats? Thanks for any help you can give me.
