On Sunday, we took the RER train from Disneyland Paris into the city. It was €7.30 per ticket and about a 45 minute train ride to the central metro station where we changed trains and rode just one stop to the Latin Quarter/St. Germain de Arts district where we would be staying (we were pretty much between the two). It was a great location. Just a 5 minute walk to Notre Dame and under 15 minutes to the Louvre, the Orsay, and St. Sulspice. We were near TONS of restuarants and food stands. So the first thing we did was find the apartment, drop off our luggage, enjoy a Starbucks Frappachino and then we went off to explore. Exploring led to a crepe stand were we had to indulge...no one in our family had eaten a crepe before and we ALL loved them.
