Hello, We will be arriving in Paris this summer on June 21st. I know the music festival is that day and from what I read there are concerts going on all around town. Has anyone been in Paris during this time? Are all the neighborhoods pretty lively until the late hours of the night? I only ask because we have scheduled a guided tour of Versailles that next day-Sunday the 22nd and are wondering if we should re-think going that day due to lack of sleep. Thanks in advance.
