Our train ticket from Paris to Nice arrived in the mail today. We got a special deal online at tgv.com which allowed us a free upgrade from second class to first class. I am assuming it was because we booked and paid for our ticket so far in advance. The train is one of those double decker trains. The trip will take 5 1/2 hours from Paris to Nice. I love trains. They are such a better way to travel than getting on an airplane. Your stress level is almost non-existent compared to dealing with airport security, the RUDE airline employees, the other passengers, crying babies...I could go on and on about how much I do not like to fly. I use to like flying. I was even a flight attendant for three years so I have flown quite a bit, but after taking trains in Europe, I realize that is the only way to travel!
