Great post! Even better I agree with nearly everything that you shared!
I happened to visit over Bastille Day (their celebration of independence) and the complimentary firework show over the Eiffel Tower was absolutely stunning! This is one recommendation I make to people who are likely to only afford one trip there.
Another recommendation is the catacombs underneath the city! It is a little creepy but certainly worth seeing!
While I didn't visit Disneyland Paris, I did take a trip out to Versailles and that was incredible as well. If you have kids I understand Disneyland but if you appreciate history at all, Versailles is worth the trip.
Look forward to your posts about other travels!
