I'm in France. Took me almost 2 weeks to open account via Internet at local brooker. Then I bought 1 (yes one) share of Accor, 2E fee. Had to call the brooker then to ask to put this share in some special "mode" (they call it here "Au nominatif administré"). Otherways you have to buy 50shares of Accor.
Once done, I went on monday to Accor site
http://www.accor.com/fr/finance/espa.../adhesion.html and I completed simple form (even if you dont speak french you should be able to do it).
However no response after 2-3 days and no confirmation email.
So I sent them also an email (to comfi[at]accor.com). And voila, in 24hours I got a response saying that my new card is on the way!
BTW english version of Accor site does not have this form to become member of this shareholders club!
So Yes, if you can get an account opened here in France you can have this platinum card for 2E fee to buy 1 share + 25E value of one share
