Because BCV is a convention resort unlike OKW, SSR or AKL there will be a $12.00 handling charge.
The reason for the charge is that all of the Disney convention resorts AKA the resorts that have banquet/meeting rooms where conventions can be held, charge a handling fee because all packages are delivered to the business center at those resorts. The business centers are all run by an outside firm not associated with Disney and the outside firm charges a handling fee to accept this packages.
