Save yourself a painful budget surprise by reading this before you start your planning...
Unexpected cost #1: paying postage
Sending out save-the-dates and wedding invitations ain't cheap - if the thought of spending your precious pennies on stamps and SAEs bugs you, consider e-invites instead.
Unexpected cost #2: AV equipment for your entertainment
If you have a larger venue, you might need to pay extra for sound equipment. Check with both your band and your venue to see what's required to guarantee a great party.
Unexpected cost #3: having your dress altered
Unexpected weight loss (or gain!) can mean your wedding gown might need tweaking unexpectedly in the run-up to your wedding day. Costs can vary depending on what needs doing but there's no harm in factoring it in to your budgeting.
Unexpected cost #4: transport for your guests
If your ceremony and reception are taking place in two seperate locations, you'll need to provide some sort of transport for guests to get from A to B. Not everyone will have the option of driving or lift-sharing, so coaches or a cute Double Decker bus might be your only option to guarantee fuss-fress transportation.
Unexpected cost #5: the reception over-running
If your reception over-runs, you might be charged an extra by-the-hour fee. Confirm with your venue if this is the case or not, and make sure your bridal party are on-hand to help you start wrapping things up in plenty of time.
