So, I am pondering taking the Canadian at some point in the not-too-distant future. I am pondering a Cabin for one vs. a Lower Berth. I know what the difference is, conceptually, but I'm still trying to pick between them (particularly for a multi-night trip; on a shorter trip, I'd probably just take the berth). Any advice on one versus the other (particularly seeing as rumor has it that the berths are likely going away in the near future, or so I hear)?
