We got them as well with our package, along with some preferred seating vouchers for using our Disney Visa.
Honestly, you really don't need the preferred vouchers for the parades, Tough to be a Bug and Muppets. We never even used them.
The ones we really liked were the vouchers for Snow White...(you stand in a separate area where there are tables and chairs and then the seats are right up front) and ToonTown Morning Madness. Those 2 I might pay money for, but not the others.
