The sticker for me is park hopping.
We have APs. We often ride a few attractions (say FOP, EE and KS in AK) and then hop to another park to ride attractions there. If we did that with this new pass, we'd have to buy it for AK and the second park. It's expensive for one park and even more so for multiple parks in one day.
I bet the offer a multi-park version at some point. The question is: How expensive will it be?
I also wonder if they will have AP/
DVC discounts. I received an email from DVC yesterday about a new program they are offering that includes Memory Maker and discounts on tickets among other perks. I'd be much more interested in purchasing the new Premier Pass if I got a discount.
