In 1989 I spent 3 days in Paris with my mum & my aunty. We camped in a tent & used the metro trains to get around, because the traffic there is a nightmare to drive in. If you visit Paris, I suggest that you park up your car somewhere safe & do the same. The public transport system is wonderful over there. Be warned though, it helps heaps if you can speak French, because most people either won’t or can’t speak English. You also need to ask crystal clear questions, because otherwise they’ll send you off on a wild-goose chase. Seeing the amazing sites there is worth the hassels though & I want to go back.
