To take a vacation of a lifetime is on every savionaire’s to-do list. Travel + Leisure’s The 100 Greatest Trips (DK Publishing; Hardcover; 288 pages; $34.95) offers many ideas on where to go. For example, this book covers which arrondissements you should visit just in case you decide that you want to show your style in the City of Light. Just remember that while in Paris, it’s important to blend in with the locals. (You are a traveler, not a tourist.) In All You Need to Be Impossibly French (Plume; Paperback; 240 pages; $13), Helena Frith Powell shares pointers on how to blend in by attaining that French je ne sais quoi.
