April 26-28, 2017 in Paris, France
2nd IEEE European Symposium on Security and Privacy
You may reach Paris by train from neighboring European countries. You might arrive at one of several train stations (Gare du Nord, Gare de l’Est, etc.) but they are all inside Paris, directly connected to the subway system: see RATP for planning your trip from there.
Depending on where you’re staying in Paris, and on your budget, you may choose from various options, combining buses, suburban train (RER) and perhaps subway.
You can reach Paris from both airports via RER line B, which stops in the center of Paris, with St Michel station being close to the conference venue. RER B trains have various schedules, with some trains not stopping at some stations. However, all trains stop at stations inside Paris (from Gare du Nord to Cité Universitaire) so you should not have to worry about it.
The system is standard for occidental countries. Just plan for the likely case where the driver does not speak good enough English.
Paris has an excellent subway and bus network, operated by RATP. The same (subscription) tickets work on bus, metro, and streetcars. If you stay for the week you may consider to buy a weekly subscription: it starts on Monday and ends on Sunday, costs 22.15€ and is valid on the whole regional network, Versailles included (bring a photo with you to get it).
Credit cards are commonplace in Paris and ATMs may be found easily. It is however advisable to carry cash for small purchases, e.g. many bakeries won’t accept cards under 10€.
