An exclusive private boat-trip on the Seine River will be organized, from 8 PM to midnight, including appetizer drink, 2h30 cruise in Paris, and banquet dinner (served seated). The loading dock will be localized in front of the Eiffel Tower.



Wednesday September 25th is kept free, to enjoy a cultural afternoon in Paris. Three different tours around Paris will be proposed to the participants, organized by the students themselves from PPSM laboratory. They will be pleased to accompany you during these pleasant moments together. Each tour, departing from Institut Pasteur, will last approximatively two hours (3 PM to 5 PM).
To help the organization, interested participants are welcome to register as soon as possible at the dedicated website. Prices cover exactly the price of transportation costs (metro tickets) and entrance to the cultural sites. Payments are only accepted in cash on the first day of the conference.
