Of course, brides and grooms and everyone else who hosts an event can do
anything they want...it's their party. But there are a lot of judgments made on both sides.
For all those who said that they did it their way and it was fine with them if people felt they couldn't come, then my hats off to you...I think you're a rare bunch. I've heard a lot of complaining over the years (I'm the youngest of 5, and the youngest cousin on both sides of the family, so I was indoctrinated early into the joys of throwing a wedding) from both sides...the party throwers and the invitees. Rarely have I not heard complaint and utter dismay about a guest choosing NOT to come, and the party thrower not having some issue with their excuse.
We were invited to DH's cousin's wedding shortly after we were married. His wedding was on a Friday at 5, two hours away...in February. And of course, there was a snowstorm. (Their reason for a Friday wedding was to give them an extra day on their week-long honeymoon.) We went because we knew there'd be a big issue with my IL's about NOT going, and at the time, newly married, I didn't want to do that. (Now, 24 years later, I'd have no problem saying "No", but still would HATE the fallout of that, because there certainly would be.) We ended up having to stay in a hotel too, because of the weather...a financial strain at the time, since we were newly out of college too. Would've at least been nice if that marriage had lasted out the year.
My wedding...ALL of my relatives were from out of state. I had my wedding on a Saturday afternoon, at 4 PM, cocktail hour immediately following, even tho we couldn't attend because we went for pictures (because yes, I think 3 hours between ceremony and reception is inconsiderate too), followed by dinner. I felt that most likely, if people came, they'd be staying over, and felt that the best time to stay over would be after the reception, rather than the night before and then drive 4 hours home afterwards. What I felt would work best for my guests was my highest priority. JMHO I would have understood people not coming that distance no matter when it was, but the best part of my wedding was how many of my absolutely favorite relatives did.
Heck, my mom even had my father's funeral at a less than attractive funeral home, rather than the one they had planned to use, because the nice one couldn't accommodate a weekend funeral (he died on a Wed)...would've had to wait until Monday, and again, she wanted to make it easier for those who wanted to come from out of state so they wouldn't also have to miss work.
