I took a couple of grown up daughters and a couple of friends to Paris for the weekend. The 2.5 hour train from city-centre to city-centre is great, tho it would have taken as long to wait for a cab at Gare du Nord as the rest of the journey. Incroyable! My experienced nr.3 daughter led us down the Metro at midnight. What surprised me was how friendly the Parisians were. Smiles in every bar and eaterie, English spoken, quite other than the Paris of old. I believe it's a conscious change and I congratulate them.
