Our Paris vacation was fabulous. Paris is the most beautiful city I have ever visited (although my international city visits are limited, I have visited a ton of American cities, the Caribbean, and cities in the UK). As far as news sources, I referenced http://www.thelocal.fr/ while were there and checked general news sites as well.
I would add that I was surprised how many young women ran along the Seine around 9-10pm. I never would advise people to do that along the Charles in Boston. The Seine was a lot busier and had wider pedestrian areas than the Charles does though.
We felt relatively safe while we were there. There were a couple of times we walked on rather narrow walkways with the most prominent danger being busy vehicle traffic. Due to recent events, if you stood anywhere for 10 minutes, three French armed military would walk by on patrol. We also drove all over the city which to some might be harrowing but I found being in the midst of various cars pointed in a bunch of different directions in a traffic circle to be somewhat amusing. Absolutely no problems getting around although our car had navigation, we also had a US/European map garmin, and thankfully for me I had my wife as the co-pilot giving directions. We also had a paris map and a France michelin atlas.
I found the Eiffel Tower vendors incredibly annoying which particularly affected us as they are like hawks around families with young kids. So much so that I would rather admire the Eiffel Tower from afar than deal with that ridiculousness. Absolutely on par with obnoxious hair braiding vendors in the Bahamas or aggressive street vendors in Mexico.
I should also note that the French people were unbelievably welcoming and accommodating with respect to the language barrier. We tried our best to mind our bon jour, merci's, etc. I tried to brush up on my HS french as well which definitely helped. There was an american with a heavy Brooklyn accent that said in a pastry store "give me one of those, I want one of those..." with a fingernails on a chalkboard grating accent and attitude. He is probably the type of american that complains about French people not being friendly. The only exception we had was at Chambord castle. The staff there had big time attitudes and practically blew smoke in our face as we exited while proceeding to chastise us for not saying au revoir after we were 20 feet past them. For how beautiful Chambord was on the outside, it had little to offer inside and the staff were obnoxious. Chenonceau was the complete opposite in how nice the staff were as well as how beautiful the property was both inside and out. There must be some story as to why Chenonceau seems to be so much better maintained than Chambord. I will have to research this.
As far as luck is concerned, I just had a great France vacation with my wife and kids. We did get stuck an extra couple of days due to the Boston storm but this can hardly be considered bad luck given we were able to extend our vacation a couple of days. It was funny watching French, German, and BBC news coverage of the storm while in France.
We definitely look forward to another adventure in France in the future and hopefully soon. Thanks for all of the insight and happy travels.
