Consider purchasing a metro pass for convenient and cost-efficient travel around Paris. A 2-day pass costs approximately €21 and travel time between locations varies depending on the destination.
If you have more time, consider adding a visit to the Palace of Versailles or taking a day trip to Disneyland Paris. If you have less time, skip the helicopter tour and concentrate on exploring the landmarks and museums in the city center. Remember to wear comfortable shoes and prepare for long lines at popular tourist destinations.
