So Disney needs to come up with a way to treat the MNSSHP ticket like a park hopper ticket. If you are paying the extra money for the extra party ticket, you should be allowed the 3 fast passes with that separate ticket, in my opinion....
I did call Disney to get clarification, wondering if I had a bad link on my tickets or something like that. The person I talked to at Disney said there are no fast passes for MNSSHP, and that it is a loophole that people are able to book the 4-7pm fast passes. He also said that if the park is full or at large capacity, Disney says that you might not be allowed in until after 7 pm. It is not a guarantee that you are allowed in from 4-7 for your MNSSHP ticket, and not to depend on that. I have never heard of anyone complaining about it on the boards, but I guess it could happen. Anyway, the option he suggested is that once my 3 fast passes are used at AK, that I have to physically go to the kiosk at MK (not at AK, not on phone, computer, etc..) to get 3 more. That is something I can do, so at least we aren't completely left out of the fast pass process.
