Flying to Bergen at 9:20 am on Sunday with my little girl. Have Navigo Decouverte, want to use Metro line 4 at 5:30 a.m. from Montparnasse to Gare du Nord, then RER B to CDG at-6:00 am because I know I need to be at the airport at least two hours in advance, even though I will check us in online and no checked bags.
Worried because on our way in from CDG on Tuesday, the RER B was delayed by 90 minutes because of an accident. No big deal as we were just coming to our hotel, but when I need to make our flight out, a delayed metro or train will make us miss our flight to Bergen.
If RER B is delayed, Taxi stand at Gare du Nord with all the construction sounds not fun. Also, at 6:00 a.m. on a Sunday, are there even any taxis there? If anything goes wrong, I doubt there will be many employees around the Gare to help us at 6:00 a.m on Sunday. Should I get a hotel at the airport to avoid a problem? Decoverte transit card can get me to CDG , so do not want to pay 55-60 Euro for a taxi from our hotel in Montparnasse Sunday morning. Thoughts?
