I am arriving at CDG on Sunday 10/7/07 (via Air France at 8:20 am). How do I reach the TGV for my trip to Avignon? Can I purchase my train ticket before I leave the US? How long will it take to clear immigtion/customs because I plan to take the 11:50 am to Avignon? I already have car rental and hotel confirmations for my stay in Provence. I will make my base in St.Remy. Is there anyone familiar with the Hotel Villa Glanum?
