I add another suggestion: avoid the family bedroom on the lower level. Windows too small.
Neither Mrs R nor I are petite (don't tell her I said that), but neither of us snore, so we have no problem sharing the lower in a bedroom. We once took a grandson on the Auto-Train and he loved the upper while we used the lower.
The sightseer lounger or mid-train observation car is a great place to see the sights.
