Is it possible to travel around Paris without a car?

I’m trying to plan a journey to Paris for a week. My family and I are from the UK, and since the French drive on the other side of the road, I am quite worried. Also, i’m the only one who can speak/read/understand french, meaning the driver cannot read the signs. I was just wondering, is it possible to get around Paris, just using trains, buses and trams? I heard that it is possible to buy a carnet de billetes for travelling around Paris, but will it last a week?

Tours within 8 hours from Paris and London's airports.?

My dad, sistah, and I are travelin’ to Canada from Saudi Arabia, Riyadh and on our way there we’re gonna stop either in Paris or London. Is there any buses to take us from either’s airports to tours while the 8 to 12 hours of waitin’ in the airport? On the way to Canada we will stop, and on the way back to Riyadh we will stop, too. Once in London and once in Paris. Please, gimme a site where I can find the prices and where I can book a ride in the bus for tours. Thanks in advance for your reply.

Love,
