Hi Carol,
Thanks for your advice re train from CDG. I think we will probably try that the next time. Unfortunately this trip, we were caught up with the computer problems in the UK and arrived at our hotel at around 22.30, due to BA cancelling our original flight.
We had no option other than a taxi from CDG which cost around 65 euros, but only took around 25 - 30 mins. Would give the train a try the next time.
