Captainplay, loosen up mate. you're making yourself very sick over nothing.
If memory serves right, I do not recall hearing a lot of spanish from those loud drunken poms lying on the beach. You can't miss them even if you're blind or deaf. They glow in the dark from too much sun and they're loud. I would tone it down if I were you. It may be a tad too much to expect to be talked to in french on a Paddy aircraft with a crew from every corner of the planet BUT having said that, maybe plain old fashioned decency when one is abroad shouldn't be too much to ask for ?? Yeah ?
Things look very different since you were travelling on the RER. It is often late, very crowded and although it remains the best way to go to CDG..........I'd stay away and find a nice little house to rent around Senlis or Chantilly. Certainly not red district like, just a lot of pretty well off families and a hoodle of pilots among them. Quite a lot of Anglosaxons too.
If you want to spend the day in Paris you can always take the train from Chantilly. In my view ??? Paris really sucks !!!!
