I think even I would take Monet's Gardens over Disney Paris. Why fly always across the Atlantic to see Disney with all the other fantastic options available to you. You can see Disney back home back home with a McDonalds, Starbucks and Burger King.
I have been to Europe six times and spent over two and a half months in Paris over the years and still want to go back to see more that I never had time to see. Please do a search on this forum for day trips from Paris. FrenchMistique put together an excellent post of the many that are possible and how the get there. He did it a couple years ago and there were at least twenty or more to pick from.
I would also recommend you spend some time here to see what else is also available in France that may be of interest to you. http://anyportinastorm.proboards.com/board/24/france
