In reply to JGarry:
Don't go anywhere near Paris. Google defaults to taking you around Paris but there are plenty of alternative routes with a near identical ETA in perfect traffic and which are far less likely to leave you with the long delays you are likely to hit going around Paris.
We usually turn off around Senlis and skirt around East of Paris, between Paris and Meaux but which route is best depends on exactly where you are staying. Have a play amending the route on google maps.
