Le Parisien is reporting that it has confirmed rumors that the RATP is killing off the RoissyBus which goes between CDG and near the Opera.
It says it will replace it with a bus that goes between CDG and another station (St Denis - Pleyel) where you can get on the metro (lines 13 and 14 and RER D)
But that is not going to be right by people's hotels in the heart of the city.
