As BPT said, it's not necessary for Europeans, so offer is limited.. Disneyland Paris does have a page with several excursions, but these are operated by third parties. Not Disney-owned, no ABD guides etc. I am sure there are companies who offer it, but I don't think you will find many people here who have used it.
People either do Paris and then the parks (or vice versa) with a split stay, or go to DLP as a day trip. If people want to do organized excursions like Versailles, Fontaineblue or even Mont St. Michel, you will find more offered from the city of Paris.
Besides that it's probably more expensive, I would always prefer to do it on my own, as with a tour guide you are on a specific schedule and modifications are not always possible.
