There are times in a man's life where descriptions of his experiences are best used to serve as a warning to others...this, my friends, is one of those times. Here are a couple of notes from my last Paris experience...
First and foremost, be sure to confirm that the latest transit union strike has been resolved prior to departing the States. If not, you're essentially screwed. Rail will not run at all, busses will be running at 1/4th the schedule, and cabs will be almost unattainable. It took us 4 hours to reach the city from CDG by bus. The highways were so clogged, I felt as though I was an extra for an evacuation scene in Armageddon 2: Electric Comet Boogaloo.
More importantly, however...leave the psychopath, flight attendant girlfriend at home. Sure, she's great in the sack...but Paris will be like the full moon to her werewolf (and not in a remotely good way). She will go bats**t nuts and take every opportunity to financially bleed you dry in this God-forsaken place.
(Ya know that previously mentioned 4-hour bus trip? You'll spend that sitting next to smelliest dude in the bus because she's pissed at you that you didn't check the details on the transit strike.)
Between the wine, the meals, stores full of expensive crap she's only seen in magazine ads, and her inability to comprehend the concept of an exchange rate...you'll eventually have to tell her "no"...and that's when the fun begins. She'll disappear for half a day having given no warning as to where she's gone (and having done God knows what or who while she was out).
In the end, you'll be tired, broke, drunk, newly single, kinda smelly, and missing your little brother's wedding in Texas by 3 hours because you missed your ride to the airport the day before while on the verge of throwing her out a 5th story window...all while spending the flight home sitting four rows apart, drinking anything the FA's will serve you, cursing "the f**king b*tch in seat 2F".
