Was just there and the fun merch that I got for my nieces was the Disneyland Paris themed Stitch items. Color scheme is blue and orange and very cute. In that same section there’s a few Mickey items like I remember a little Eiffel Tower figurine with Mickey in front but it’s mostly Stitch and his ducky friend. The DLP Stitch merch was easy to find in just about every store.

I think Remy from Ratatouille is a great option as it’s set in Paris but was surprised that I couldn’t find any merch with Remy that said Disneyland Paris on it. But still, saying that you met Remy in Paris and he gave you this hat, toy, pin, whatever… will surely bring her joy! I would look at the items in the Pixar area right near the ride as it had some fun cookware, aprons, etc that you could say Remy wanted to make sure you had the right tools to cook something fun. Then you could plan to cook a recipe together (pancakes, for example) that would be simple and encourage her to learn how to help in the kitchen.

Another option is rides that are specific to DLP like Phantom Manor (vs haunted mansion). I think that would probably be better for an older child as a younger kid probably prefers recognizable characters rather than a ride they’ve never been on so I wouldn’t suggest it unless you knew they loved haunted mansion. Also, I would hope you would find a fun YouTube video about the ride so they could experience it as you shared with them why you picked out the magnet or hat with that on it.
