This is not park related but you guys are amazing and I figured you would know. After we are done at Disney we were going to take the RER into the city. I won't know which stop to get off at till we book our airbnb but once we do that because we are going to have our luggage I was going to get a taxi or lyft to the house (unless we get lucky enough to get a house next to a metro station) but then when we head to southern france we need to get to the Eurrail station. I was looking and we need to go to Toulouse and it said to take the TGV at Gare Montparnase. Is there a metro train that takes you to that station? And if we don't have internet on our phones I am assuming we are stuck with Taxis since we can't use the Lyft or uber app? Sorry to have so many questions but when I look it up it has been a bit confusing.
