Continuity

I'm not sure if that's the right word, but so be it. Anyway, Wedding Crashers has been on HBO about a million times in the last couple of months, and after watching bits and pieces of it over and over and over again, I have a couple of questions:

1. The day of the Cleary wedding, the schedule apparently includes: The wedding, the reception (including pictures), a boat trip to their home on the coast, a football game, so hangin' around time, then dinner. My question is, what time was this wedding, 8:30 in the morning? Weddings rarely start before noon, and the reception was off-site, which means it probably didn't start until 1:00 or so (at the very earliest). You gotta figure that went at least four hours, so now, if everything is breaking their way, it's 5:00. I gotta figure that rounding everyone up and sending them home, then getting on the boat and cruising to their pad after everyone has left is at least another hour. So now it's 6:00, they've probably been up since 6:00 am for an early wedding, and they're still going to play football before cleaning up for dinner? Without even questioning whether they'd even eat dinner on a night like that (I mean, if you have an afternoon reception, chances are you aren't having a big sit-down dinner that night). I find that all highly improbable. Also, no one was drunk, which makes it probably the lamest wedding reception I've ever seen.
2. After the falling out, Owen Wilson and Vince Vaughan don't talk to each other for weeks/months. Umm, aren't these guys business partners? How can you just not talk to your business partner for that long and still have a business?
3. After Vince Vaughan marries Isla Fisher, the four main characters drive away, impliedly to crash another wedding. Wouldn't you think they'd have, ya know, a reception of their own to attend? (and they were definitely leaving the wedding, because it was only like 2:00 pm).
4. Why wasn't the chick who played their secretary at the beginning in the movie more? She was the hottest one! Bastards.
   

Otherwise, pretty funny movie.
