Versailles is worth of seeing. Althought I had bought this ticket before going, I had to wait on the same line with those who had not bought the ticket, for 2 hours, but everything went quickly as I had nice people around the line. We had nice conversations and they kept my place while I went to Ladies room. So, be social there! Reserve the whole day for visiting Versailles, it is a huge place inside and outside. So gorgeous rooms and Royal Opera. On a warm day, hats are useful at the Gardens. Reserve also water to drink. There is a restaurant and cafe inside the Palace, delicious food and pastries. I recommend, I ate pasta, took cappuccino and strawberry cake. There is a little train going to other sightseeings inside the area, to the lake, where people can hire a boat to row, to Maria Antoinette Palace etc. It was 8€, round trip. Nice experience just to relax. I did not see the fountain show, but they were playing so wonderful music in the Gardens, which warmed my heart.
