We are also longtime AP holders from Northern CA. I am also feeling some uncertainty about what our future at DL will look like. We were there in early June for AC opening and had a great time. Our next trip is over Labor Day weekend, and I admit feeling some dread. I thought it was busy in June but all the reports I'm reading are that it is much busier. We may upgrade our tickets to Magic Key, but it will depend on the lead time for park reservations. If regular tickets get us 120 days and MK is only 90, we'll be sticking with regular tickets. We tend to go over big weekends so not being able to book for Thanksgiving or Christmas would be an issue (we were Signature + AP holders).
I don't like the park reservation system and the hopping restrictions, but I could maybe put up with those IF they helped to control crowds. From the crowd levels lately, it doesn't seem as if that has been happening. But the biggest thing missing in the MK program for me is MaxPass. I don't think we'll be visiting DL nearly as much without it. My fear is that Maxpass will become a very expensive add on for all the MK passes. The monetizing of FP at
Disneyland Paris does not bode well IMO.
