Hello,
Your visit should be quiet unless the french schools break up for half term. I have been in both March and April, In and out of school time and we have had nice weather too.
I'm not sure if the Disney Hotel is still holding the dance down the stairs( characters descend down the stairs in the reception and then do a meet and greet, saves a lot of queues)It's only on 4 days a week but well worth visiting, I can not remember but I think it's Thursday to Sunday, may be someone can confirm. They also did the same thing with several princesses, but I'm again not sure if thats still on

I would also attend the magic hours, you will find Buzzlight year, Peterpans Flight, Teacups, Carosell and Dumbo open. We walked onto all these rides without any queues, and if your hotel does breakfast in the park you can do the rides and stay in the park for breakfast.
Where's everyone by

Just my Kids by the Castle and this was during August school holidays
I have heard that Dreams is running until Sept 2013.
Hope this helps
