For comparison sake, we did the Eastern France tour 2 years ago. It is not cheap, but there was so much included in the itinerary.
As regards the food, we did not find the need to spend that much on our own. We were happy with the food at the group meals, although one family out of our 28 was not. On two occasions, there was enough food leftover from picnics that people didn't even go out to eat. Some would bring a bottle of wine, someone else would have cheese, sausage, crackers or fruit to share and we just enjoyed a relaxing meal. That tour has lots of wine tasting opportunities, so many didn't order extra wine at meals. If there was going to be a group meals, we were frequently satisfied enjoying a sandwich and the time to see more of the area rather than a sit down meal.
This tour, our 4th RS, had such variation - there's champagne tasting in Reims, but you can also see The Museum of Surrender (WWII) or the cathedral light show at night. There is a solemn visit to Verdun, and a wander in Alsatian vineyard. You can see the breath-taking Aguile Midi as well as the breath-taking Theater of Orange. I could go on, but hopefully this gives you an idea of the tour.
Bottom line, you won't go wrong either way.
