* Fly into Paris and explore the city.
* Take a train to Provence and explore that area
* Take a train to Switzerland. Visit a few cities and mountainous places there.
* Finally take a train to Paris and fly home.
How much time do we need if we go by this plan? We only have 2-3 weeks (we’re hoping that’s enough). We want to fill each day with as many activities as we can. We don’t want to be rushing and traveling too much. I know that the more time we have the better. Thank you for your help!
