According DLRPToday, Disneyland Paris’ E-Ticket system has now been integrated into select FASTPASS machines across the park. At both Disneyland & Disneyland Paris, you can buy and print out tickets online before arriving to the park (just like most airlines). It’s a neat system; you save time in line waiting to buy tickets, Disney saves paper and staff. Now these printouts are first-class ticket citizens: at DLRP they can be scanned at FASTPASS booths just like regular tickets (prior to this, they gave out these blank FP cards, quickly found on the black market–aka eBay). In Disneyland, if you bring a printout, an official ticket will pop out when pass through the gates that you can use for FP booths.
Definitely interesting to see if this at-home printing option comes to WDW. While it’s hard to imagine a sheet of A4 surviving a ride on Kali River Rapids, wouldn’t it be rad to skip the ticket booth and the hotel lobby sign in process? Just print out your sheet(s), check-in online, and get a text with your room number when it’s ready.
