I'm experiencing similar frustration.
I have an AP and made a reservation for my daughter and I at Coronado Springs from Thursday through Sunday. My daughter's ticket is currently on order through Chase (employee discount). On Sunday, her father arrives and we're then going to stay at Marriott Grande Vista. He has a ticket on order from Chase as well. Needless to say, I can pre-set my FP for Fri-Wed (according to
MDE site), but I can't do it for my daughter since we don't have her ticket yet. I guess there is just no point to me having a FP reservation if I can't get hers until her ticket arrives and I tie it to the reservation. As for the Marriott stay, we haven't reached the 30 day mark yet so I'm not sure what will be involved with that.
My biggest frustrations are:
1) The added stress the uncertainty of what will happen when we arrive. I feel like there will be at least 1 hour on each of the first few days to fix issues. A bit glass half empty but I can't shake this sense.
2) I don't like the amount of time that needs to be invested pre-visit on figuring this out.
3) Assumption that the time invested in pre-planning is OK with people.
