I'm planning to visit Paris in April and was wondering if you could help me decide what ticket to buy in order to travel with public transport. I'm travelling on Tuesday from Charles De Gaulle airport to my hotel, address 149 Rue Legendre and going back to the airport on Saturday. Between those days I also go aroung Paris a lot. Which would be the most reasonable and cheapest way to go? It would be great if the ticket consumes RER and metro.
Thank you so much!
