Insight is an outstanding tour company. We have been on 5 Insight tours. None of the tours have been to France, however. We have been to Paris on our own and have found the French to be rude to Americans. They seem to forget who liberated them duringg the second world war.
Well with THAT attitude no wonder they were rude to you. I did not find the French at all rude,busy,yes,rude,no.But I was treated the way I treated them.
We were not rude to the French. My wife is not a rude person to anybody. We have learned that if you spit honey rather than vinegar, you will be trated accordingly. The French just haven't learned this yet.
