How to Arrive
Getting to Hôtel du Parc from Paris Charles de Gaulle Airport (CDG) is really very easy, fast, and inexpensive, which I think is one of the reasons this hotel is so great. All you have to do is take the RER B train (it's the main one to take from the airport) towards Paris for 15-20 minutes. Aulnay-sous-Bois is one of the first big stops. From there, it's only a 2-minute walk to the hotel, which of course is perfect for people leaving very early in the morning or arriving very late at night.
If you’re coming from Paris Orly Airport (ORY), it’s easy too. You take the OrlyVal automatic shuttle train to the Antony RER B station, then take the RER B northbound and change at Aulnay-sous-Bois. Total journey time is about 50-60 min.
This hotel has to center of Paris (Gare du Nord, Châtelet–Les Halles or Saint-Michel–Notre-Dame) a direct 20-25 minutes ride by RER B train. The direct line makes it very convenient to go into the city during the day for some sightseeing and then return to the hotel in the evening. A car is definitely not recommended for this location, which is set up perfectly for public transport.
