I'd like to know all the options for the transportation between CDG airport and your hotel (Hotel Residence Hotel). I know there are three options:
(a) taxi from the airport
(b) RER train from airport to Gare du Nord, then taxi to the hotel
(c) RER train to Gare du Nord, then Métro (line2, then line 13) + 400 meters walk.
I want to know the average prices for each, knowing that we are 5 family members with 2 bags (if the taxi charges extra for luggage). I need to know specifically the prices of RER train tickets and the price for metro tickets.
