Couple of "shining" moments from my brother's wedding....
There were only seats for the immediate family (so, about 15 chairs) during the ceremony- everyone else stood on what was essentially an elevated platform and watched from there. Ceremony was held in a private home, so there were couches and chairs scattered throughout the rest of the space for comfort and relaxation during the reception, but during the 25 minute ceremony, approximately 75 people were left standing.
HC did photos before the wedding, but during cocktail hour, did a few extra before going upstairs so the bride could change into a different dress (wedding ceremony and photos gown was a beautiful mermaid trumpet gown with a sweetheart neckline; reception dress was a knee length, one shouldered/one sleeved loose white dress), leaving all guests at loose ends and making conversational efforts. Fortunately, SIL is an event planner for a swanky chain of restaurants in TheirCity, and her company catered the entire thing at cost, so there were plenty of nibbles and beverages to try out during the cocktail hour before dinner was made available.
One guest (Brother's landlord at the time, and old high school acquaintance of our Dad's), made a complete jerk out of herself the whole night. First by showing up in ridiculously inappropriate attire for the wedding (think billed as semi black tie/formal evening attire, and she showed up in a casual "day at the beach" dress that looked like it hadn't been washed in weeks), then by haranguing SIL's assistant/coordinator half the evening when she mislaid her purse behind a sofa, practically shrieking that someone had stolen it (yes, she had too much to drink. No, her husband didn't do a darn thing to try and calm her down while we hunted for the purse so that Brother, SIL, and other guests would be able to continue enjoying the party without listening to her).
She was later apparently quite unhappy when she learned that I had a) gotten married, b) not invited her, and c) had invited another lovely lady whom she and my Dad knew from high school- said lady had been my father's grade school sweetheart, he escorted her to prom, attended her wedding 50 years ago, and he and my mom sat with her and her husband all through the trial of the drunk driver who killed their only son during his first month as a highway patrol officer. This lady has known me since birth, and has always been a delight. The jerk acquaintance was left to stew in her own juices, though when she and her husband sent us a belated congratulatory gift card, I of course responded with a polite thank you note immediately.
The limo buses Brother had arranged for us all to take back downtown to the hotels were a bit late, but otherwise, a good time was had by all (including DH, then FH, who still giggles about some of the wedding events that weekend, but does continue to apologize to me- he had waaay too much to drink at the wedding, and while he held it in until we got to our hotel room, I did have to spend an hour cleaning him and the bathroom up and shoving him into bed. His hangover the next morning, as I understand it, was quite spectacular, and he was deliberately very very careful not to indulge much at our own wedding for fear of "facing my wrath"
