A couple years ago on a morning radio talk show, the topic of weddings came up and how to pull them off on a tight budget without offending anyone. Many of the stories were pretty interesting and proof that it can be done. As an example, the lowest price one was the cost of the license and cake. Invites by phone and held at the couple's home. The "most expensive" was around $3000 with restaurant catering and grocery store flowers in a church. These were all in a pretty expensive to live area.
As for ones I have actually attended, the majority were cake and punch in the evening with a dj optional. The most extravagant budget wedding was mid-afternoon in the local church with platters from Costco to make a meal. Again all of these in the same high cost of living area.
On the same token, there's always one wedding where no one thinks of the guests.
What experiences have you had a guest?
