Book excerpt: When Connie Emerson's low-budget guide to Paris was first published, it quickly sold out. This newly revised edition, based on recent visits to the French capital proves that the term Paris bargain is not an oxymoron. Though the City of Light has a deserved reputation for being one of the world's most expensive destinations, it can be a cost-cutter's delight. Hotel rooms go for far less than established rack prices to people who take advantage of special promotions. This also applies to airline reservations, car rentals, or even restaurants. Charming and reasonably priced bistros dot every corner of this remarkable city. Readers will find sound advice on shopping, places of interest, senior citizen discounts, and places to entertain children (many free). Also included is a guide to the best and most effective routes for the Metro or the bus. This invaluable resource shows thrifty travelers how to get the best value for their francs.
