The holiday season is all about giving and sharing. It just so happens that by practicing these acts of caring, event planners can shave some bucks off their budget, too!
When booking your event venue, ask the on-site contact about what other events are being held prior to yours. Is there a chance you could snag their leftover supplies and decor? If there menu is similar to yours, ask about having the same food served so that the chef doesn't have to spend time and money purchasing separate ingredients and preparing something different.
This "sharing" with other events cuts back on what the venue has to do in order to prepare for your party, and this will be reflected on your final bill. Another benefit: reusing decor and making the most of ingredients reduces waste at your party.
