1. St. Barts

Ignore those photos of celebrities living it up on big yachts. The high-season glitz is but one facet of the friendly, casual Caribbean island of St. Barthelemy. Book a flight on economy carrier JetBlue into St. Maarten, just a 10-minute puddle-jumper ride from St. Barts (you'll also see it as "St. Barth's"). Rent a villa, and cook your own meals. Beach-hop the free public beaches with a picnic of bread, cheese and fruit from the supermarket or from one of the island's wonderful traiteurs (takeout joints). Visit during the annual soldes (sales), the twice-yearly official French sales seasons, for deeply discounted wares.

2. Paris

Yes, you can make the City of Light an affordable travel location. Here's how. Paris has plenty of reasonably priced one- and two-star hotels that are light on amenities but heavy on charm. Alternatively, rent a guest room in a Parisian's home through a rental agency such as Alcôve & Agapes, Airbnb or My Apartment in Paris. It's utterly free to stroll one of the world's grandest boulevards, the Champs-Elysees, or admire the blossoms in the Tuileries Gardens. Buy an economical Paris Visite pass for unlimited travel on the city's subways and buses. Dine the "bistronomy" way, in smart, relaxed bistros offering hearty three-course meals for under 40 euros.
