Hee! Ok, I've got to admit that I was misled into taking the wrong shuttle bus, nonplussed by the bus-from-terminal-to-airplane "system", and puzzled by the lack of signage, but merely thought "what the heck? I'm in Paris!", and shrugged it off. If I was a bit more of a masochist, I'd book my next French vacation through T1 or T2 just so that I could see what the fuss was about.
