Set the date
Marry during your destination's shoulder-season. Try Aspen in summer; head to the Caribbean from mid-April to the end of May, or go to the Mediterranean from September to October.
Choose less-expensive destinations. For example, Napa Valley is a less pricey alternative to the vineyards of Tuscany, while French-speaking Quebec City will cost less than Paris.
Ask your airline and hotel or resort for a reduced group rate. Many travel companies will oblige if your guest list is ten or more people.
Hire a local wedding planner, who can save you time and money.
Support the local industry, and you'll save big on shipping costs. In Hawaii, for example, choose indigenous flowers instead of roses, which must be imported.

Don't just look at resorts: smaller bed-and-breakfasts might be able to offer even better packages.
Explore travel insurance options like Medjet (medjetassistance.com). It will cost you up front, but if you become seriously ill and need to be flown out of a remote destination, you could save thousands of dollars.
