estherschindler, I don't know the answer to your question, but may I respectfully suggest you check the Fodor's Travel Forum. They have over 50,000 members and many many active members who travel all over the world. Paris is a favorite destination and there are experienced people who will undoubtedly give you advice.

If that doesn't work, just go to www.fodors.com and click the European Travel Forum. First type in "train station storage" or something like that in the search window. If you don't find your answer, post a question but title it "Gare du Nord or Gare du Est storage" so the right people read it. Sometimes people can be a little testy (or just plain rude) on Fodors, but most of them are genuinely helpful and I'm sure someone will answer your question.
Good luck. Sounds like you will have a very exciting day in Paris!
