Having a vendor cancel last minute can be stressful, but remember that it's out of your control. This is where having a backup plan comes in handy. Contact your other vendors - they might have recommendations for alternatives. Check with your venue, as they often have a list of preferred vendors. If you have a wedding planner, they will be invaluable in finding replacements quickly. Finally, understand your rights based on the contract you signed, including any refunds or compensation due to cancellation.
