hscottm,
Roissybus leaves CDG (bus stops in front of Terminals 1, 2 and T9) for Opera Garnier every fifteen minutes from 6:00 am to 11:00 pm, and takes 45 minutes to an hour, depending on traffic. Of course, with a strike, you can expect traffic to be much heavier to/from the airport. The cost is 48FRF one-way. From Opera Garnier you can catch a taxi to your hotel.
Return service is from 5:45 am to 11:00 pm
