Are you arriving at terminal 1 or terminal 2?
According to the
RATP itinerary planner, RER B to Chatelet, line 4 to Montparnasse, and line 12 to Volontaires will take about 50 minutes (though changing lines in those large stations will definitely take longer than the 3 and 1 minutes it quoted, so I would say a minimum of an hour).
It also proposes Bus 350 to Porte de la Chapelle metro, then line 12 to Volontaires. Estimated trip time: 1 hour 10 minutes.
Another option: Roissybus to Opera, then Bus 95 from Auber to Procession (essentially just around the corner from your hotel). This looks like it takes about 1 hour 45 minutes, though.
Air France bus to Montparnasse, then Bus 95 from Montparnasse to Procession (AF bus transit time plus 12 minutes for Bus 95).
Also RER B to Luxembourg, then Bus 89 from Luxembourg to Alleray (also just around the corner from your hotel). 1 hour 6 minutes.
I probably haven't covered all of the options, but there are more than I would have imagined!
