My family will be visiting Paris for the first time in Aug for 4 days, Thur-Sunday. Our children are 8 & 9. We would love to have any tips on the best days/times to visit certain attractions, and any other great advice on travel with kids. We'd like to spend a day (or half day?) at Versailles, which would be the best day for that? And is it better to try to see the popular sites on Thur or Friday, or will the weekend be better, since a lot of Parisians will be on vacation anyway? Just trying to make the most of the time we have. Main things we want to see/visit are Eiffel, Arc de Triomphe, Montemarte, Jardin de Luxemburg, Notre Dame, am i missing anything great?
