Trying to figure out the best way to get from our Marais hotel to Orly airport on a Sunday morning. It looks like there are a number of options. Which would you recommend? Thanks!
If your flight doesn't leave super early, take Metro line 5 to Gare d'Austerlitz and the RER C from there to Pont de Rungis-Aeroport d'Orly. The fare from anywhere in central Paris to Pont de Rungis is €4.00. Take the airport shuttle bus from Pont de Rungis to Orly. The fare is €2.50. Taking the RER B to Antony and the driverless Orlyval shuttle train from there to the airport is another option, but it's more expensive (€2.50 from anywhere in central Paris to Antony and €8.40 for the very short ride on the Orlyval).
