We recommend you book your hotels as soon as possible as the French Rivera is a very tourisitic region.
Shuttles will be organized on June 8th and 9th from Nice inner city to the different event venues. The shuttles will leave from the Square Albert Ier, by Avenue Max Gallo so we would recommend you pick a hotel no far from this meeting point. Please find below a list of hotels.
