We've been home from Italy four days now and my jet lag fog has lifted enough for me to start planning our next trip. We'll be joining a group for a 12-day trip beginning in Vaison la Romaine and heading north to Ardèche Gorges, Tournon-sur-Rhône, Lyon, and Fuissé. From there, transportation will be provided to Macôn-Loché TGV station.
So, here's my question. We'd like to add around two more weeks to the trip. Normally, we'd head straight to Paris and spend two weeks there. My concern is that the organized trip ends April 9 and I'm thinking that we'd be better off heading south for better weather. We've already spent a week in Avignon, Arles, Lyon, Cassis, Nice and St-Jean-de-Luz, so those wouldn't be good choices. We're "slow" travelers who enjoy wandering through old towns, taking photos, and getting to know new places. We usually look for a day trip or two from our base. We could fly, but we'd much prefer going by train. We haven't traveled at this time of year, so I'd very much appreciate your thoughts on one or two places where we might enjoy a week or two. Or, any thoughts on Paris in April?
