I much prefer the train anyway.
NO 'Security' bag search (normally - when I have travelled in France anyway), get out of your seat and go for a walk when you want to, have a beer or two in the bar, or numerous coffees if that's your style, enjoy the scenery - you can actually see it thru the BIG window....AND.....
Depart and Arrive - in the MIDDLE of town..!
What's the fuss..?
