I happened to be on the flagship eastern France tour in 2009. Although there were itinerary bugs to work out, which they have since done, this was an amazing tour. It was educational, informative and simply incredible scenery. I loved our guide (William) and met some wonderful people that I still stay in contact with. I did that tour single and my new boyfriend and I took the best of the Adriatic tour last June. It was his introduction to RS and he really enjoyed it. He loves France and wants to take the Eastern France tour above all of the other France tours that Rick offers. It was that great of a tour and with the changes, I know that it will be fun and exciting for me for a second time. We will take it next year, as Italy won out this year. My friends that were on the tour with me in 2009 agree that they would also take it again.
I have never taken a tour of or been to the areas in the other France tour, but I can assure you that you won't be disappointed either way. Rick's tours and guides are so great and you will enjoy either choice that you make.
