TGV has decided to simplify things for people travelling in Europe by train. The Raileurope service will now fall under the banner of TGV, the high-speed network that connects France, Belgium, Germany and Holland. I just had a quick look at the prices from Paris, which range from €43 to about €92 one-way depending on time and the availability of promo prices. The journey takes about 5 hours but has the enormous advantage of bringing you straight to Cannes station, a 10-minute walk to the Palais. So you skip the 40-minute trip from the airport and the extra expense. If you have never taken one, the high-speed trains are a great way to travel. Check for available times here
