Thank you to everyone that has posted information about Paris! All your "insider" tips have been great, and I have learned a lot which will be very helpful during my trip to Paris next month. I know detailed posts take time, and I am sure your efforts are appreciated by many. Thank you especially to jerrymorgan and NYCWS10025 - incredible detail!
I am staying at the Renaissance Le Parc Trocadeo for the first half of my stay and then transferring to the CE (you sold me jerrymorgan) for the second half. I am trying to decipher the correct RER/Metro lines to get me to Le Parc from CDG, and I am wondering if anyone knows the correct route. I know the best Metro stop for the hotel is the Victor Hugo. Thank you for your help.
