French currency is the euro, abbreviated EUR. For 1 USD you get approximately 1 EUR. There are lots of currency exchanges offices in Paris city centre, however, proceed with caution. Credit cards (Visa and Mastercard) are widely accepted, usually even in small shops.


230 V, 50 Hz. Plugs of type C and E (also compatible with type F).

Tap water

Tap water is safe to drink.


Tips are always included in the final price. Additional tipping is therefore unnecessary.


The streets of Paris and Marne-la-Vallée are safe. You should however exercise standard caution, as you would do in any large city especially around the very crowded areas. In the case of an emergency, dial the all-purpose emergency number 112.


Most people speak English to some degree. All shops/restaurants in Paris city centre should have someone with decent English.


Public transportation is very well developed. We recommend using the metro to get around in Paris, and the RER to travel between Paris and the station Noisy-Champs.

There are several variants of the tickets in Paris. We recommend buying the transport pass or installing the transport application, on which you will be able to load tickets you purchase, such as:

  • One-way, 90 minutes tickets (2,10 EUR, or 16,90 EUR per 10 tickets) valid within Paris
  • One-way tickets between Paris and the station Noisy-Champs (up to 5 EUR)
  • One-week tickets (30 EUR) valid from Monday to Sunday
Please keep in mind you have to validate the tickets and that standard paper tickets may no longer be sold.


Taxi fares are determined by the law. We recommend booking your taxi online (through your favourite app) or through your hotel, as to avoid any misunderstandings and know in advance the price of the ride. There are also taxi stations at which you can enter a taxi. Never enter a taxi whose driver does not show you their valid licence!
