Here's the (approximate) translation:
FNAC proposes a private evening: Terrorific Night at Disneyland®Resort Paris
Evening (from 20h30 to 01:00) reservec for FNAC customers, visit the parc under privileged conditions (limited capacity) and (re)discover the attactions in a new visual and musical setting... and come dance on a gosthly dancefloor animated by a DJ!
Try the scariest Halloween party... Too late to turn around! The 25 October 2008, the Walt Disney Studios Parc will host exclusively the Terrorific Night. A unique experience with distressing events, reserved for some privileged ones...
It goes on to talk about the ToT, and again about the dancefloor. It also recommends to leave your children at home.
And says that with the ticket you get free parking from 18:00
Normal price is 29 euros, and you get a 2 euro discount if you have the FNAC card - but it does seem to be open to everyone! You're a FAC customer if you buy from them...
That sounds really good fun! Wish I could go...
