I took my 12 and 14 year old daughters (plus the misses!) down to the Dordogne in the summer in the
MCC. We all fitted in ok with 1 weeks luggage although there were a few moans after the 9 hour journey back to Paris - mostly due to numb behinds rather than lack of legroom/elbowroom/headroom though. I'm 5' 10" and the rest of the family are regular size for their age I'd say!!
