I've been to one where the couple got married in the Bahamas. They had a reception a month after they returned. They had a dj, appetizers, open bar and she wore her dress. She wanted to get as much use out of it as possible.
I'm liking the idea of a brunch with breakfast foods, mimosas (so we have an excuse to drink champagne) and bloody marys and people can just stop in when they want:)
