3. Seating snafus.
After the victory of compiling (and finalizing) your guest list comes the challenge of seating arrangements. It's part art, part science: Who will combust next to whom or become fast friends?
How to deal: If your guests' elbows touch and they can't easily move in between tables, you've probably crammed too many of them in one spot. Also keep centerpieces at a conversation-friendly height (no one wants to stare into an orchid all night). If you're having a hard time divvying a group of friends or family members equally, try to seat guests within the same vicinity so that they can lean over and "awww" together during the first dance instead of texting across the room.
Table numbers with fun facts about the couple serve as a great conversation-starter.
