Wedding days are stressful long before the actual day, but when it arrives, the pressure mounts 10 fold. You've spent months managing every detail down to the minutia and now all those decisions come to fruition. There's bound to be some hiccups in every wedding, but they are mostly small problems. Every now and then a major issue comes up throwing everything into turmoil. As the bride and groom, everyone's looking to you for answers, so take charge.
Identify the Problem
When disaster strikes, step 1 is always identify the problem. Is it one major issue or several issues happening at one time. For example, did the caterer forget to show up or did the ring bearer lose the ring? Did your mother say something to the maid of honor that made her mad and now she refuses to leave the dressing room?
You can't solve a problem without knowing what it is. Also, keep in mind that the real problem may be different that the most obvious. If the maid of honor refuses to leave and you don't know why, then you may need to replace her last minute. If you can find out why, maybe an apology from your mother can help coax her out. Don't underestimate the importance of identifying the problem.
Stay Calm and Delegate
You're stressed to the max because it's your wedding day. That alone is enough to put you at unease, but when something goes wrong it's easy to slip into panic mode. Staying calm is an important aspect of any problem solving. You can't make rational and informed decisions if you're freaking out on everyone. You're not only the bride or groom, but also the leader. Seeing you freaking out freak out everyone else..
Also, you have a massive support system around you. Your groomsmen and bridesmaids are there to help and don't be afraid to delegate tasks to them. If several things need to be done to solve a problem, then tell them to do it. You're just one person and you can't handle everything yourself in a timely manner. If the officiant is broke down on the highway, then send a bridesmaid to get him while you fix a rip in your dress.
Decide if you Need to Make an Announcement
Ideally, the problems can be solved quickly with your guests none the wiser. You're a machine of decision making, but it's not always up to you. If the caterers delivered everything to the wrong place or if the reception venue refuses to have an open bar, even though it should have been included in the rental contract, then you'll probably have to make an announcement.
If it happens at the reception hall, then use the DJ's or band's sound system to address the crowd. They'll likely understand and won't grumble too bad if they know what's going on. There's nothing worse than the whispers and shouts of an angry mob that hasn't eaten and doesn't know what's going on.
Your wedding is an extra special day, but that doesn't mean there won't be problems. Follow these steps and no matter the issue, you'll be fine.
