Versailles with a baby thoughts: you are not allowed to take your stroller inside Versailles palace or any of the other buildings. This was clear on their website. It is easy and quick to check your stroller or any other small bag at the entrance. We used an Ergobaby baby carrier and it worked great except that Harris is a particularly hot-natured baby and it was a warm day. There was a decent breeze flowing through the palace, but it was crowded and stuffy. Harris had enough of being hot after about an hour which was only about half through the palace. After the palace, you may collect your stroller for the gardens. We did not do this as we wanted to do the other buildings, but this was a mistake! The other buildings also have an easy stroller check with no additionally queuing. There is quite a bit of walking around the grounds, even if you take the petit train out to Petit Trianon and Grand Trianon. The stroller would have made everyone much more comfortable. An even better option on a warm day would have been to rent a little golf cart which you can drive to all the other palaces and around the grounds. They were all rented when we arrived. I believe it was around €30/first 2 hours, plus additional for more time but I can't remember. This would not only have been a slightly cooler option to the queuing in the sun of the petit train, but also much faster. There is too much to see at Versailles so any time spent waiting in lines is wasted time. Even without kids the cart seemed like it would be the way to go.
