Yes! There are a lot of us! My final bill for my Wishes wedding is just under 12k, inclusive of taxes and fees and an Epcot photoshoot. However, the minimum for morning weddings has gone up to 12k, but it can definitely be done.
PrincessSarahK had a BEAUTIFUL wedding for under 20k. I think her BEO is posted in the Budget thread, and check out her PJ!
