Have you been to DLP before? Take time to visit the DLP forum from this board.
We went last year and they do have the best castle ever. The MNNSHP is very scarry indeed. We loved the haunted house.
That being said, it lacked the magic that we have in the States. The CM's are very different. We did look for the best in everything but won't go back to DLP on our trip to Paris this year.
Enjoy Paris and all there is to offer!
