'Reservations' in Egypt are a misnomer...even holding an advanced
ticket doesn't guarantee anything. If I were you, I'd head to Ramses
station and buy your ticket cash money. If you have some flexibility in
your itinerary, you can take the risk that the train is full. If you
don't have flexibility in your schedule, this ticket will be the least
of your problems while in Egypt g.
