Tip #1 : Stay away from Holidays unless they have a special meaning to you. As in Tip #1 vendors can and most will add a surcharge.
Tip #2 : If you don't mind getting married on a week day ie - Thursday, Friday or even Sunday. You could be looking looking at a saving a few dollars. Most vendors will give you a discount for picking a "non" wedding day ie - SATURDAY..LOL.
Tip #3 : Is there is a curtain flower or theme you are wanting? If your favorite flower is only in season a curtain part of the year you could save money by choosing a date in that season. To fly in flowers during an off season could an can get expensive. DO NOT have a Halloween themed wedding in April! If you want a Halloween Themed wedding please do it in October.
Congratulations you have a chosen a date!
~ Happy Planning
