Regarding "That's French for Great Deals" [April 27]: Going from the Roissybus drop-off point at Rue Scribe to the other side of Paris can be one pricey taxi ride. The Air France bus goes to more locations -- Gare Montparnasse, Porte Maillot, Etoile (beside the Arc de Triomphe), Gare de Lyon, and between Charles De Gaulle and Orly airports. It's plush, air-conditioned, extremely comfortable and open to all travelers, not just those who fly Air France. See www.cars-airfrance.com.
Travelers taking the RER B train from the airport to Paris should have luggage no wider than about 20 inches across, or they won't be able to fit it onto the escalators.
Also, take precautions against pickpockets on the train, and consider keeping one's passport and money inside clothing. I've never had a problem, but it's easy to underestimate what jet lag can do to a person's street smarts.
