Ooh! Ooh! I remember this thread being really helpful when I was planning my wedding, and now I can add my own post...
Our Custom/Wishes wedding came to $10,070, plus tax and service charge, which worked out to $11,586.56 total. (This varies for everyone depending on what they pick, since not everything gets tax and/or service charge).
We only had 34 people though, and no DJ, no centerpieces, no bridesmaids, and brunch. Plus, we had outside photo and video. But the number does include a dessert party, a friendship boat, and the MK photo shoot. Oh and lots and lots of charter buses...
