Has anyone taken the Behind the Scenes Tour of the WDW railroad? My dad is a train buff and we thought it would be fun to take him on the tour but at 84 years old, we're not too sure if it's the right thing for him. He's very active and mobile but if it is three hours of standing and walking, that might be a bit much. We're going in October so we aren't concerned about heat, just him being on his feet for that long. Is the tour broken up with periods of sitting during presentations or such? Thanks.
