It's a great deal! A ticket from Kansai Airport to Namba Station costs 970 yen, so it's totally worth it for trips to Wakayama or Koyasan. Redeeming the ticket is also very convenient; basically, the station staff scans the QR code and you get your ticket. The ticket is anonymous, and you can use it on two separate occasions, or even on your next trip to Japan within the same year.
