When I asked about this new VR experience at Versailles, no one responded and I couldn't find reviews anywhere so a friend and I decided to make a day of the gardens and do this. We found it very rewarding. Few people seem to know of the VR experience. While we waited for our session many people wandered in and were told they had to get tickets on line or at a ticket booth elsewhere.
Unlike Eternelle Notre Dame you do not wear a heavy backpack with the VR gear and so kids can do this one. It is time in a very small room and about 10 people or so at a time and everyone wears a headset and can walk about during the experience.
Le Notre guides you to several places in the gardens that have long since been destroyed including the menagerie, the labyrinth and a grotto of the gods. The most fun was probably the menagerie where you can wander among exotic birds and watch them flying overhead, be charged by an elephant and have a tiger walk right by you in petting distance. The labyrinth is interesting but you don't get to really walk the whole thing. The grotto where Louis XIV also appears is interesting. The whole thing lasts about 25 minutes or so.
If you enjoy VR experiences it is well worth doing. Not quite as amazing as the Impressionist visit to the Salons at the Orsay last year, or Eternelle Notre Dame but close.
The gardens of course are always a delight on fountain day -- we waited to get our tickets at the gardens which was a mistake -- get them on line ahead and you just walk in and it is a euro cheaper. The fountains seem to run longer than the last time we did this type visit but the triple fountains was not functioning when we got there.
Lots of people renting boats on the canal and the open air restaurants were pleasant and offer good service and good food.
