We are arriving in CDG. Our hotel is Hotel Bellevue on Rue Pasquier. We (2 persons) are considering taking the Roissy Bus which will drop us at Opera. Google Maps shows that it will be a 700M walk to the hotel. We will each have one large roller luggage@20kg . Is it easy to walk to our hotel with roller luggages? Are the pavement smooth or cobbled? Or are we better off taking the RER as Gare St Lazzare station is just opposite the hotel? Thanks!
