For this question, please add up all your wedding costs and divide by the number of guests. That's more accurate than comparing the costs for 50-person weddings to 10-person weddings.
Include location fees, wedding coordinator, food, alcohol, florist and other decorations, DJ, photographer, tips for all your vendors, and any other expenses related to the wedding day itself EXCEPT attire.
It seems there was a lot of confusion over at the "How much do you think your destination wedding will cost?" thread about what costs to include or not include, and someone suggested breaking down costs by categories, which I think is a great idea. Site administrators, I hope I'm not stepping on any toes! Don't mean to, just seemed like people were confused.
