The airport has Terminals 1, 2, and 3. Within the airport, the free CDGVAL airport shuttle goes between Terminal 1, Roissypole/Terminal 3, Parkings Pr /Px and Terminal 2. You have a direct access to the hotel from the parking PR.
Allow plenty of time to get to the gate. Even after check-in and going through security, shuttles and walking to your gate could take 20 to 30 min.
