Versailles has really never been high on my list of places to go in France because I am pretty much nauseated by certain types of opulence, but for many it is an obligatory France thing to do so when in Rome I did as the Parisians do....or something.;) It is big, it is pretty, it is grand, and all of the things you might expect. If you are in France you may as well go there, but honestly I had more fun riding my bike around Paris than hitting all the tourist spots up because it's just such a cool place to BE in.
Points of interest
I enjoyed seeing Versailles but much prefer "everyday" activities in the city center
