I just had this same situation. Free dining package starts on 11/24. I was told I couldnt get FPs for the room only bookings I made for 11/22 & 11/23 as package tickets started on 11/24. I could activate them when I arrived and use them on 11/22.. at 60 days out from 11/22, I could not make fast passes, as expected, but I tried online help/chat and they went into system and assigned complimentry fast passes to AK 11/22 and HS on 11/23. i gave him a list of options and times. after that he said I should be able to go in and make FPs for the rest of the week which I did, got everything I wanted...
No one said this was an option... try it
