PS don't let the trains in Paris scare you. Just memorize the color of the line by your hotel and the names are associated with the direction in which they travel. For example say the yellow line runs from Smith to Jones, just remember if you left for the day heading towards Jones....you'll find your way home by getting back to the yellow line and heading towards Smith until it hits your stop. (it took us forever to figure that out lol) I WISH the names were as easy as that but no such luck lol. I can only assume that this is how all trains work, but I don't live in an area with anything like that so I'm an idiot
Needless to say, by the time it was time for us to leave, we had it all figured out like pros.
Going to Disneyland is pretty straightforward. You take the local trains to one of the central RER train stations (it's a different type of train than downtown) and head towards Marne-la-Vallee/Chessy and ride it alllll the way to the end and it will drop you off just steps from the turnstiles! It's kinda neat to ride through the "regular" sections of Paris where you would guess the Walmarts would be haha! Then you get to see a little countryside and DL is out there in the middle of nowhere. Man you're making me want to go!!! If you have any questions just ask! I loved it, and it was so affordable that I went back the next year too! I'm like a pro now. lol
