I have read past posts on this subject and it really seems the majority suggest Metro 14 as being the fastest/most reasonable cost. We are in our early 70's though fit and able to walk easily, ect but we will each have 2 pieces of luggage plus our man/woman bags to keep secure. How easy is it to navigate between the train-metro and then metro-train with baggage/feeling secure in mind. We will have at least 3 hours so taxi time should not be an issue. Should also say that we will have already spent 5 days in Paris so at this point should be familiar with using the metro (we are going to Caen from Paris, spending 2 nights and then back to Paris and on to Switzerland).
Thank you for any suggestions on this matter.
