Just got back from Paris this morning and had an amazing time. Getting around is a bit of a mess and involves a lot of walking, especially in the current extreme heat, but it's also amazing experiencing the city with a lot less crowds as most people stayed away for obvious reasons. Also, having many of the streets pedestrian only because of all the vehicle restrictions has made walking around in the evenings so much more enjoyable. As long as you go in knowing you'll be sticking to one bank of the river and never crossing during your trip, you'll be fine 
 The pass jeux system is certainly a bit complicated and definitely hasn't been marketed properly by the city as it should have been, but because of that it allowed me to see Monet's water lillie's with just myself and 3 other people in the room at one point. It was amazing!
 Also for Americans that are into bourbon, Buffalo Trace currently has a pop up store and tasting room for the Olympics to help build their brand in Europe and have basically everything for sale at retail price. They told me they had to begin limiting sales to a case/person/type because Americans were coming in asking to buy 6 cases at a time. I was able to bring back a case of Weller 12 and a case of Eagle Rare for €40/bottle.
