We are booked for our first trip to DLP next July. Our hotel is in the city but we are planning a two day visit to the parks. Not being accustomed to a train system for transportation (we are from the States) and not speaking French (although I'm learning basic phrases) my biggest concern is using the rail system. I understand about the Metro and RER but it is still something so different for me and I'm worried I may make the wrong selection, board the wrong train, etc. UGH!
