Reporting back from MUC…. We would have gotten through CDG in a flash except for one little detail I omitted from my OP: we had bags to check. The wheelchair got us ahead of most of the throng at check-in and, after a few minutes' wait, through security and to our gate.
The assistance at MUC was exceptional and we made it from the satellite terminal to our gate at the far end of terminal 2 while having a pleasant conversation with our athletic aide.
Thanks again for the advice.
