I'm going to La Defense in February. I have found out that I can get the RER B train from CDG to La Defense, however I am struggling to find a timetable for this route. Are they regular enough for me not to need one?
Also, does anyone know if La Defense station is within walking distance on the Ibis hotel La Defense? Their website isn't particularly helpful and doesn't actually mention La Defense station at all.
Thanks for any guidance you can give :)
