Hope you enjoy doing the full up & back…. The day separation should help. When my wife & I made the full up & back on the train on the same day, frankly I was ready to get off that rocking & rolling train about 1/3 of the way back. We didn’t see anything on the return trip we didn’t see going up, so the bus ride back was looking much more appealing to me. The roadbed isn’t in the best of shape, of course which is historically accurate.
