Most venues will accept EMV credit and debit cards (i.e. Chip & PIN), at least VISA and MasterCard. Swipe-only cards can be more tricky (it has been illegal for banks to issue them for years in France, so only foreign visitors use them). American Express is widely but not universally accepted. Diners/Discovery, UnionPay, JCB, etc. are mostly only accepted in shops catering to tourists.

Community day

If you subscribed for the community day, you should have received instructions by e-mail.

Meeting point is at EuroDisney at 9:45. The theme park opens at 10:00 and closes at 21:00.

We will leave from the park at 18:30

How to get there

The best option is to take the Metro/RER. This takes approximately 1 hour and 5 minutes:

  • take metro Line 13 from the hotel to St Lazare, then
  • take metro Line 3 from St Lazare to Havre-Caumartin (1 stop only),
  • take the express train RER A to Marne La Vallée-Chessy
    • check on the platform display before boarding: not all trains go to Marne La Vallée-Chessy!

N.B.: You should buy a ticket to Marne La Vallée at the metro station. The ticket is valid for the entire journey.

Evening drinks

We will meet at a bar, in front of the hotel, for drinks (soft and beers), at around 20:30.

Payment

The local currency is the Euro. Merchants are forbidden from accepting other currencies (except exchange).

Most venues will accept EMV credit and debit cards (i.e. Chip & PIN), at least VISA and MasterCard. Swipe-only cards can be more tricky (it has been illegal for banks to issue them for years in France, so only foreign visitors use them). American Express is widely but not universally accepted. Diners/Discovery, UnionPay, JCB, etc. are mostly only accepted in shops catering to tourists.

Best change rates are close to the Hotel, Metro Bourse, Vivienne Street.

Transportation

NOTE: VideoLAN does not refund taxi expenses nor car rentals.

Paris-CDG / Roissy airport

Important note: there are works on the RER B line at night until Friday, included. The RER B service is interrupted between the airport and the Aulnay-sous-Bois station at 11pm. There is a replacement bus available but this incurs a much higher trip time. More information: http://www.transilien.com/contents/fr/Docs---PDF/Travaux/20150720-B-Roissy-2007au3010bis.pdf

The electrical system is 220V / 50Hz. If you come from outside Europe, please make sure your devices are compatible beforehand.

Internet

Hopefully, there will be Wi-Fi.
