Hello all, yes I am a newbie

Although I have been to Disneyland Paris 2 times before we were once caught out once with a French public holiday. Although it did not ruin our time (as we were there a few days) it did mean queue times of over 2 hours at times.
I am oplanning another trip in March this year. I have checked the school holidays in France and seen they are in three zones, and the dates were are looking at is in the zone C (Paris, Versailles, Bordeaux) holiday times.
It may seem like a stupid question but will this dramatically increase the amount of persons in the park ordoes it not have a huge impact in the same way the holdidays do in the U.K? If they do then we will have to have a rethink on our plans which is a shame as its for a specialbirthday.
Any advice would be very much welcomed!
Thanks peeps!
