Following a very enjoyable trip to Paris last year for the Arc, myself and my parents are heading back again this year. I was looking for places to stay and spotted the Marriott in La Defense. Last year we got on the wrong bus from the track and ended up in Port Maillot instead of Port d'Auteuil. Does anyone know if the buses go frequently from Port Maillot to and from the racecourse as the Marriott is on the tube to Port Maillot and could be very handy to get into the centre of paris in the evenings. Marriott is €109 a night but if anyone has any other ideas I'd be delighted to hear. the place we stayed in last year was a bit cheap and cheery and wouldn't mind spending around €100 a night on the accomodation.
