It’s a moderately good hack, but it isn’t of infinite versatility, barring the addition of a bit more cheating to get around the sleep/food problems.
I think we can let Harry sleep. For example
Instead of drawing a tally mark on his arm, Harry punches a hole in a ticket.
Original Harry doesn’t set up chairs in seats 11-20. Instead, he puts a rolling hospital stretcher where chair 11 would go, and leaves 9 empty spots where chairs 12-20 would go. The rolling stretcher has pillows, an empty sleeping bag, and a slot into which you can place a ticket.
When Original Harry moves the trunk to the hallway, he finds 9 stretchers lined up against the wall. Every stretcher has a ticket, and the tickets have 12, 13, 14… 20 hole punches. The stretcher are heavy, like a person is sleeping inside the sleeping bag. Original Harry moves these 9 stretchers into the 9 empty spots he blocked out earlier.
Original Harry puts on his conductors hat and waits for passengers. One of the passengers is Tired Harry, whose ticket has 11 punches. Tired Harry places his ticket into the slot on empty stretcher, climbs into the empty sleeping bag, and goes to sleep. Now all 10 stretchers have ticketed Sleeping Harrys.
On arrival at 5:00, Conductor Harry adds a punch to the ticket of all 10 stretchers. He removes the 10 stretchers from the trunk, and lines the first 9 up against the wall. The last stretcher, with 21 holes punched in its ticket, Conductor Harry stashes in the Great Hall.
At 5:30ish, in the Great Hall, a newly Refreshed Harry wakes up. He gets out of his sleeping bag, picks up his ticket, and continues the day.
