I virtually always stay near l'Opera in Paris and take the Roissybus to and from CDG, but I have a one night stay approaching in which I'll be arriving after noon to Gare de l'Est and going to the ballet at Bastille that evening, leaving the next morning from CDG, and am thinking about staying near Republique. As I will have some real luggage on this trip (Paris is just the last night of the trip), I'd prefer to avoid the RER to CDG (IIRC, step-free access is at best difficult to find at Gare du Nord and in any case the RER station at CDG is about a mile from 2A). Is Bus 350 a viable option? I gather it makes a number of stops, and I've seen the route, but how long realistically would it take? I'd want to be at 2A by 9:30 am on a weekday, so would be traveling in rush hour.
