We're elderly and haven't been to Paris in more than 45 years. We're on a cruise which ends in Southampton and I'm thinking this is our chance to visit the great city again. Problem is that we'll need a driver/guide when we're in Paris, both to be reminded of the wonders of the city itself and to get to places like Versailles, Giverny, etc.
I know that there are dozens (hundreds?) of tour companies/guides. I'm hoping that people can suggest which are "the best"? I think we'd prefer to be in some sort of small group than to have a private car. The visit would be early September.
