Just got an email from Disney Paris. Mostly stuff we already knew, but I think this is new?

Just book a package to arrive any day as from March 30th, 2007 right through the celebration, and your kids under 7 years old will be offered free hotel accommodation (in any Disney®, selected & associated hotels) and free entrance to both Disney® Parks.
