I've been to Versailles before but it was as a single so I didn't really care about lines, etc. This time I'm taking my niece (last part of June) and wondered if people have suggestions on the best way to get into the palace without having to stand in the unending lines? Also, has anybody ever taken one of the tours and found it useful or just taken the RER out there and did a "do it yourself" tour instead? What are your thoughts/opinions? Thanks!
