You've spent a year or more planning this amazing day that is your wedding - how is it possible that anyone could hate anything about it? Having been on all 4 sides of the wedding spectrum - planner, bride, bridesmaid and guest - it's my opinion that the ceremony is 100% about the couple and reception is about the guests.
That's not to say the reception shouldn't infuse the couple's story, personality, etc. into the party somehow, but this is a time to show your appreciation & over-whelming happiness that everyone was there to celebrate with you. Tasty food & drinks, fun entertainment and a solid timeline are just a few things that guests appreciate.
