My wife and I will be taking our twin 13-year olds (boy/girl) on their first trip to Europe in July, which will kick off with 4 nights in Paris.

My wife and I have been to Paris a number of times, but we want to do what I jokingly call "Tier 1" highlights with them. E.g., Louvre, Versailles, Notre Dame, Catacombs, etc.

For some/any of those, we're interested in a guide to make it smooth/more informative. Appreciate any info or recs!
