Disneyland Paris have a link on their website to contact their dieticians. They promise to have breakfast/lunch/dinner available for any children/adults with allergies, which will be suitable for them.
My DD is allergic to dairy, egg and nuts (peanuts) for which she has an epipen and going anywhere like this usually stresses me out slightly because I will have to carry all of her food with me.
I emailed them last week (our visit is at Easter) and haven't had a reply yet. Not sure whether to try again.
