Flight
It is easiest to fly into Paris. There are two airports in Paris (CDG, ORLY). CDG has a train station where you can easily connect by train to Saumur (www.sncf.com). Train journey is ~3 hrs. Saumur is the neighboring city to Vivy, where all festivities will take place.
Rental Car
You may also rent a car through your company of choice. The drive from Paris-Vivy is ~3 hrs. Renting a car may be best because Vivy is in the countryside, making transportation within a bit difficult. Having a car will also allow you to do tons of sightseeing before or after the festivities :)
