Is it easier to take the RER or the Metro 1 from the La Defense Hilton into the city proper?
I will be in Paris for a week (June 25-30). Will be going to Giverny one day but other than that hope to take in the sites of Paris - La Tour Eiffel, Montmartre, Mus�e d'Orsay... Would like to be on foot when possible but also want to buy a metro pass (or whatever is easiest) to get back and forth from La Defense, even if it is somewhat more expensive. Thanks for your help.
