I went to a wedding this past summer for a close family friend, and they had over 600 guests. It took two hotels to house everyone, each level of each hotel had a courtesy room filled with gourmet food, each hotel room had a big basket of welcoming items, the rehearsal dinner was for over 100 people at a ridiculously nice country club, the church itself could only hold 170 people, so only the family members could attend (everyone else attended the reception), the reception took up TWO FLOORS of a hotel, there were god so many tables, with elegant food, three huge cakes, multiple bars, and a huge portrait (literally, over 7 feet tall) of the bride in the reception room. And in the morning, they held a big breakfast for everyone...and come to find out, they also held ANOTHER dinner that night for 200+ people. My Mom made it very clear to me that I will never, ever see another wedding like this in my life, and she is no doubt darn right, lol. It was a huge greek family, a big greek wedding (harhar), and while it was immensely fun (lots of dancing, lol, lots of umpa-ing), that wedding was well over $180,000. It was the most ridiculously, though amazing thing I've ever seen.
I think I'll just take a nice little party, no ceremony, but amazing food for everyone...
