I know it was just mentioned, but try getawaytoday.com
They have up to 8 day hoppers, which comes with an early entry day They are incredibly fantastic with their service and prices. I cant say enough about this company. Its well known on the boards here. If you give it a shot, just call them up and talk to a service rep. Its much easier then booking online which is another alternative.
Yeah thats what they do.. getawaytoday sends you a confirmation slip/receipt and you bring that to the main gate ticket booths at Disneyland, and they give you the hoppers there.
