RATP once offered free entry to Disneyland Paris for your birthday. It was straightforward, and we tested it firsthand to bring you the details.
Registration took just 2 minutes on the RATP Privilege website. We provided our date of birth, mobile number, email, and that's it.
Minutes later, an email arrived with a free one-day pass to both Disneyland Paris parks.

Everyone—even non-RATP users. The form asked for a transport ticket number, but we selected "No ticket" and still received the invite.
Our test confirmed it works without a pass! :-)
Register by December 30, 2011. Tickets were valid for your birthday week in 2012.
For a March 3 birthday, entry was good from March 1-7, 2012—even if your 2011 birthday passed.
Print the emailed invitation and present it at Disneyland Paris entrance. It swapped for full access to both parks.
