Which value resort are you staying at? If the only thing you hated last trip were the buses, you could stay at either Art of Animation or Pop Century, then you get the Skyliner to two of the parks.
If you have a Chase branch near you, open one of their checking accounts for the bonus and get the Disney Debit card. All the same discounts at the shops, online and the "exclusive" meet and greet areas.
