My husband, 2 children (12, 14 yrs) and I will be arriving at CDG on a Sunday AM, about 10:00. What transportation would you suggest? We will be staying very close to the Place Monge metro station. We could take the RER and then transfer to 7 metro, but I have heard that transferring at Chatelet les Halles may be more than we want to deal with after an all night flight. Other options would be the Roissy bus + 7 metro to Place Monge, or RER to St Michel-Notre Dame and taking a taxi the remainder of the way. Any thoughts or opinions would be appreciated.
Also, we leave Paris from CDG at 10:30 on a Saturday AM - what's the best way to get back?
