Landing Gear,
Thank you for the additional information. I added some profile info. I'm in Washington DC, but will be flying in June (I know its a bit off, but I'm coordinating efforts for a family vacation for 10 people) via Houston (Delta Award tix) on Air france. Currently, the flight ends up at Terminal 2E.
I looked at the Orange link you gave. As you suspected, they will only ship within France.
It seems that the best option will be for everybody to buy Orange cards in the airport, and just exchange phone numbers once we get to the hotel. I was hoping to find a way to get cards and numbers in advance, but you made some good points about having the vendor set up the phone and using Orange directly instead of through a third party.
Thanks again for the help.
Shane
