The less stress you feel on your big day, the more fun you'll have. Great planning helps you avoid forgetting important details. Avoid these stumbling blocks that threaten to ruin your happy day:

1. Not prioritizing your budget on the important things. The banquet is over, and now the party begins. If the majority of your reception time will be spent listening to music and dancing, it makes sense to allocate a proportionate amount of your budget to the vendor responsible for your entertainment. Whether it's a band or a DJ, the key idea here is quality.

2. Not communicating with your vendors. Have a thorough conversation with all of your vendors, and let them know EXACTLY what you expect. Don't assume that, because they are professionals with years of experience, they automatically know what you want. Each bride's vision is different. Vendors want to avoid disappointing you, so share the details of your dream with them from the beginning.

3. Not communicating your needs and expectations with your bridal party. Let each person in your bridal party know, prior to your wedding day, where they are supposed to be and when. Important moments at your reception can't be rehearsed, so prepare a timetable for your bridal party that includes the Grand Entrance, speeches and toasts, bridal dances and any planned photo opportunities. They will be grateful for your organization.

4. Waiting until the last minute. Finish everything on your checklist at least two days before your wedding. You don't want to be scribbling place cards at 2 a.m. on your wedding day. Give yourself and your groom a task-free day or two before the wedding to relax and rejuvenate.

5. Having too much to drink early in the day or the night before. Not only is it a good idea to avoid alcohol until the final party hours, it's best to stay hydrated by drinking water or other non-alcoholic beverages. If you can't resist a good nip, be sure to eat something.

6. Spending too much time taking pictures. There are the photographs of special moments you MUST have, pictures of spontaneous moments that are FUN to have, and staged photos that become a nuisance. Don't be afraid to say NO to your photographer when you've had enough.

7. Losing your perspective. Keep your mind on what the day is about, and on the things and people that are really important to you. Don't get bogged down in so many details that you forget to have FUN! If something goes wrong, try your best to take deep breaths and think about the big picture. Don't let the little things that might go wrong ruin your night. Above all, keep your sense of humor!

8. Getting stressed or overwhelmed. Eat! Talk! Dance! Have Fun! Keep things simple. After you've greeted your guests, let them find you if they wish to visit.

9. Not planning an exit strategy. Assign end-of-the-night tasks to others you trust, so you can leave unburdened. Final duties might include gathering gifts and transporting them “home,” paying the hall, and removing decorations -- including flowers, centerpieces and other wedding notions.

10. Immediately leaving on your honeymoon. Try not to plan a 6 a.m. departure the day after your wedding. Give yourselves a day to recuperate and get your things together. Better yet, go back to work for a week before leaving on your honeymoon.
