Just helpful tip on Navigo-Roissy Bus

My husband and I recently returned from a 10 day trip to Paris. We were traveling with one large suitcase and two smaller carry ons. At the onset of our trip we purchased the Navigo/week long pass. We arrived on a Thursday and we were able to use it through Sunday for travel. Then renewed on Monday for unlimited travel (Zones 1-5) on Metro/busses (and can use on funicular at Sacre Couer). . .So for the trip into Paris we just took the Metro and of course had difficulty with our luggage (really tried to pack light but oh well!). But upon returning we heard about the Roissy Bus near the Opera Garnier...We asked our hotel if our Navigo pass would work on the bus to the Airport they said no that it was a different company. We googled it and found information that said Navigo could be used (Zones 1-5). To be sure we asked an information desk at the Opera Metro stop and they said no. Finally on our day of departure we figured we'd give it a chance and it worked! You can use your current valid Navigo pass on the Roissy bus. It was so much easier with the luggage we had and wished we would have known on our way in since we stayed not far from the Opera stop. And we were dropped directly at our terminal- it stops at each terminal at CDG. Hope this is helpful to someone out there!
