To my knowledge, we do not have this at Disneyland Paris. We barely have Photopass. They did add photopass opportunities for the covid reopening last year and I assume they will keep that.
Also a recent addition is a department to help with proposals, weddings are fairly new. You can contact them to see if they can help with something, but keep your expectations low.
I get an error when trying to open the special celebrations page, but there is a mailadres on here, maybe they can refer you.

I dont know where you are from, but keep in mind November in Paris can be cold, rainy and windy. Probably not the best time for an outside photoshoot.
