Along with the (privately organised) trip to Monet's garden and pond in Giverny, this was one the most memorable and wonderful experience from our trip to Paris.
My wife and myself appreciated picnicking on the grass at the end of the grand canal of Versailles and having a far-distant look to the castle.
(After enjoying nature and some intimacy there - it had been a real shock to line up in the queue and masses at the main entrance for the castle and its mirror room etc ... but this is a totally different stroy)
Nick had been a terrific tour guide.
We can definitely recommend that tour - it's really great.
