Decorations are critical for establishing the atmosphere of any event. Depending on the location, you may be able to use the space's natural beauty to save money on the décor. However, if you do need to amp up a dull conference area, consider adding some furnishings to the dessert or buffet tables. Just make sure the decorations you choose don't conflict with the overall style of the event. For example, if you're having a black-tie get-together in a fancy hotel ballroom, strobe lights probably aren't the best option. Floral arrangements often are the easiest and most adaptable choice for making a plain space look great. However, flowers can get expensive and there are other options that require less money. A single votive or tea light candle at the center of each table, for example, can go a long way.
