You can buy a Navigo week pass up until 23:46, the last RER B train to depart CDG Terminal 2 train station for Paris.
The Navigo card will be good until Sunday midnight. On Monday you can use a single-use RER ticket from Orsay Ville to Disneyland (Marne La Vallée station). It will cost 11.60€.
You can buy both the Navigo card/week pass + RER ticket for Orsay-Ville to Marne la Vallée from the airport train station ticket office when you arrive at CDG. The RER ticket is valid to use anytime in the future.
