When it comes to wedding venues, locations, and vendors, you’re dealing with a fixed cost. The best way to cut your budget is by trimming your guest list. Think of it this way: you've got tables with ten guests each; even if the linens, table, chairs, and ten place settings are included in your reception site cost, you've still got (for example) one $150 centerpiece and ten $50 meals to serve (plus approximately $15 worth of drinks per person). With those numbers, just ten guests could cost you $800! Hence, cutting just one table full of guests from your list can save $800.
You may also want to consider a winter wedding if you live in a colder climate. In most parts of the country, the "deep" winter months -- January, February, and March -- are the least popular for weddings (June, August, September, and October are the most popular, but December has been gaining fast because of the holidays). Because there's less demand, you'll likely get discounted prices on your wedding reception site -- not to mention most of your other wedding services, like catering, photography, and flowers (except around Valentine's Day and Easter, of course, when roses and lilies are at a premium because they're in high demand).
