[Idyllchat] A side trip from Paris to Renne, what to do with our luggage

[teacher2sandy at fastermac.net]

We (myself, my friend and my mom)  are ending up a 30 day
stay in Paris and heading to Renne to spend the weekend with
my son. We do not want to haul all our luggage on the train
to Renne and the back to CD airport.  I have called hotels
and they won't keep it due to security concerns.  I was
referred to the airport terminal 2 but have been unable to
call them. I also sent a e-mail to NW airlines for help. 
Now I ask here, please, any experience with this type of
luggage proble?
