Couple (74 & 84 respectively) are taking an organized bus tour of France next July. Tour ends in Monaco. Afterwards, we want to take a train(s) to Aix-en-Provence, then after a few days, the TGV to Paris (already checked Rail Europe's website to have an idea of timetable, knowing it'll change by July). We both speak French.
Trying to decide if a 2-day rail pass is the best way...or buy the tickets individually. Don't want to get a cheap ticket that is non-refundable since one never knows what the future may hold. Didn't see on the website a place where I could ask them direct.
