This was a Viator day tour. Picked up at our hotel, Giverny in the morning, Versailles in the afternoon, lunch on the way, all arranged and paid for well beforehand, before leaving Australia. One advantage: avoiding the long queues to get in. Not really a "conducted tour": it was more like "Here are your tickets, present them over there, then go there, and there, and I'll meet you here at twelve o'clock". (Or four o'clock after Versailles.) We were not prepared for the jostling crowd in Versailles, where we had no real choice except to move along with the pack, with little opportunity to say "ooh" and "aah" at anything. And it rained hard, and I had to wait a long time in a queue in the rain to retrieve my backpack. Giverny was slightly better, and the rain stopped after we had walked through Monet's garden in a very wet crowd with umbrellas. Still, the driver was polite and punctual, drove well, spoke English, and the lunch was exellent. My advice: Put Versailles well down your piorities list: you can find much more accessible and less tourist-infested chateaux away from Paris. Look at my Valençay gallery; we had that place practically to ourselves.
