If you think you will be getting a lot more on a personalized, private tour, I am begging you to hold on to your wallet because there is ZERO return on this investment. Just take the larger group tour! That way, if it doesn't meet your expectations, at lease you are not out hundreds (or in our case, over one thousand) dollars. Our family of 5 (2 adults, a young adult, and 2 teens) LOVE tours and museums. We were SO excited about Versailles and splurged to the tune of $1,100 on a private tour hoping that it would be worth it... it wasn't. We woke up at 6am and travelled by train from Paris to get there almost 30 minutes early for our 9am tour. Our guide didn't arrive until 9:25 saying he was told the tour began at 9:30 although all of our information said 9am. At 9:15 when we still didn't see him, we tried desperately to get in touch with the tour company but their phones are disconnected and no one ended up answering our emails, even days later. We were relieved when our guide finally arrived at 9:25. He was then confused about what tour we were taking and said the company didn't give him the right tickets. After we had been waiting nearly an hour, he had us stand by a map for another 20 minutes with a rather boring, uninspired beginning of a tour. He never even introduced himself by name, or asked us anything about ourselves (where we were from, what we might most be interested in hearing and learning) which was totally different from any other tour we took where the guide will spend a few minutes introducing him/herself. With a private tour, you would think he'd be interested in asking us where we were from? What we were interesting in seeing/hearing? But no... he had a canned version of a tour he wanted to give, and that's what he did. So, after waiting for him to show, spending 20 minutes listening to nothing of interested, we then stood outside of the gates for an additional 20 minutes while he sorted out the tickets. By the time we actually walked INTO Versailles and saw our first room, it was 1 hour and 15 minutes after the tour was supposed to officially start. We had signed up for this tour, which stated in writing: 2 hours in the palace, 1 hour in the gardens, and 2 hours at Marie Antoinette's Trianon. Our ENTIRE tour was only 3 hours and 45 minutes, NOT 5 hours that we paid for. While the guide was nice enough, it was unfortunate that he wasn't quite our cup of tea, but we acknowledge that is mostly subjective. The real issue we had was paying for 5 hours and getting 3hrs. 45 mins., and the unresponsiveness of the local tour company (not viator). This is, in my opinion, a RIP OFF that takes advantage of eager tourists who want to see Versailles. We spent a lot of hard earned money, went into it with an open mind and eager heart, and did not want to be critical. It was literally just THAT BAD. :(
