Has anyone upgraded the 4 day Costco tickets to a Disneyland annual pass? I'd like to know the value given. Was hoping to use the tickets over Thanksgiving weekend, which is blocked out, then upgrade on the last day, but it would depend on the value. If it is higher than the cost of a SoCal Select annual pass, $269, I would have to pay the difference to go to a SoCal pass, which is $60 more.
