We will be arriving at ORY at 7:10 am and must get to CDG for a 11:00 am departure. I am concerned about the traffic delays. We would like to take the Air France bus. Will this work at this time of day? Assuming we miss the 7:30 at ORY and catch the 8:00, the "normal" 90 minute trip would take how long at this time? Is two hours realistic (i.e., arrive at 10:00)? If so, is an hour enough time in CDG to check in, check luggage, etc.?

Thanks for any help/advice.
