Tax and service charge
DO NOT count toward your minimum. Setup and delivery fees DO count toward your minimum.
So figure if you can bring your wedding in right at the $10,000 minimum, there will still be $1,200-$2,000 on top of that in service charges and taxes (the amount depends on which elements you pick b/c not everything gets tax or service charge).
From the DFTW website:
Wedding Expenditure
The following minimum expenditures
(excluding tax and service charges) must be met to host an event at the WALT DISNEY WORLD Resort.
