Taylor Swift and Travis Kelce's wild wedding weekend could include unusually long 'cocktail hour'

"Yes, cocktail hours traditionally last one hour," said Florida-based etiquette expert Jacqueline Whitmore in response to reports about the unusual length of the pre-wedding event as part of a whirlwind day that could last into the late hours of Friday evening. "This gives the newly married couple time to take pictures, and it gives the guests time to socialize and relax."

But "sometimes," she said, "the cocktail party can last more than an hour if the wedding party is quite large, running late - or if guests and the wedding party have to travel quite a distance to the reception venue."

Roughly 1,000 guests are expected to attend - with many described as "high profile" and "VIP" by the police department. 

The reported schedule is igniting debate, however.

"Hospitality is measured by comfort, not by the clock," said Lisa Mirza Grotts, a California-based etiquette expert and founder of Golden Rules Gal.

She also said that today's weddings "are less about following a timeline and more about creating an experience. Traditionally, the ceremony came first and the celebration followed. Today, many couples are reimagining that order."

When a bride writing on Reddit asked about her own planned two-hour cocktail party, many commenters had strong opinions.

"So cocktails are from 4:30-6:30? That does seem like a long time," one Reddit user said.

"I think two hours is [way] too long. One hour should be the cap for a cocktail hour. You can sneak away for the sunset photos during dinner," a third person chimed in.

A fourth said, "There's a reason it's called cocktail HOUR, and not cocktail two-hours! You could push it to 90 minutes if absolutely necessary, but two hours is definitely too long."

"Seems a little long! I'd be exhausted and people may get very drunk," yet another said.

Whitmore said etiquette rules are in place for a reason.
