I sure wouldn't waste time out at a Paris airport-what would most people pay for just one night in Paris?

You can take the Air France bus into the city round-trip for about $20, even if you don't fly on Air France.

For further tips on the bus and Paris, check-out the best Paris website I've found, Bonjour Paris. It is at:

They charge for some of the content but a bunch is free, including the discussion boards which are loaded with info.
